Cordless Power Tools Attributes

Cordless power tools — drill/drivers, impact drivers and wrenches, rotary hammers, grinders, ratchets, band saws — move through industrial MRO distribution to maintenance crews, plant engineering, fleet shops and contractor accounts. The purchase is rarely standalone. The buyer is usually extending a battery platform already sitting in the tool crib, so the platform decides the sale before any spec does.

The data is hard for reasons specific to this category. The same 5-cell pack is marketed as 20V MAX in the US and 18 V elsewhere. Torque arrives as in-lb, ft-lb, Nm and the unit error "ft/lb", and one supplier's "Max Torque" is a fastening figure where the next supplier's is breakaway. The numbers buyers ask for — vibration ah per EN 62841, weight per EPTA-Procedure 01/2014, head length — are declared in the manual PDF, not the price file.

Then variants multiply. One impact wrench ships as bare tool, as a 2×5.0 Ah kit, as a 2×12.0 Ah kit, and in hog-ring and detent-pin versions: separate MPNs and GTINs, identical headline torque, nothing in the record to tell them apart.

Core

Every SKU needs these. Without them the record is not a product, it is a row.

Tool Type
enum
Impact Wrench, High Torque

Top-level facet. Impact driver, impact wrench and hammer drill are not substitutes, and each carries a different spec set below it.

Battery Platform
enum
Milwaukee M18 REDLITHIUM

Packs do not cross brands. The crib's existing platform screens the catalog before voltage, torque or price are considered.

Voltage, Nominal
number · V DC
18

The comparable voltage figure. Marketing voltage (20V MAX) and nominal voltage (18 V) describe the same pack and must not share a facet.

Sold As
enum
Bare Tool (Tool Only)

Bare tool vs kit is the single largest price driver in the category and the most common cause of a wrong-line PO.

Batteries Included (Qty)
number
2

Separates 2967-20 from 2967-22. Without it a bare tool and a kit are one indistinguishable record at two prices.

Battery Capacity Included
number · Ah
5.0

Drives runtime, weight and price. A 2.0 Ah kit and a 12.0 Ah HD kit of the same tool are different purchases.

Chuck / Drive Size and Type
enum
1/2 in Square Drive

Determines what the tool accepts: square drive for sockets, keyless chuck for bits, SDS-Plus for hammer steel, 1/4 in hex for insert bits.

Manufacturer Part Number
identifier
2967-22

The number the buyer quotes on the phone and the only reliable key across supplier feeds, punchout and the OEM's own site.

GTIN / UPC
identifier
045242551286

Required to list on marketplaces and to match a variant, not just a model, across syndication.

Differentiating

What buyers actually compare on. This is where catalogs win or lose the filter.

Motor Type
enum
Brushless

Brushless vs brushed governs runtime, service interval and price tier. Buyers filter on it more than almost anything else.

Max Fastening Torque
number · ft-lb
1200

What the tool applies driving a fastener down. Must be stored with its unit and its basis, never as an unqualified 'Max Torque'.

Max Breakaway Torque
number · ft-lb
1750

Nut-busting figure — what loosens a seized fastener. Higher than fastening torque and the number maintenance buyers actually spec on.

No-Load Speed
range · RPM
0-400 / 0-1200 / 0-1900

Stated per speed setting on multi-mode tools. A single top-end number hides whether the tool has a controlled low range at all.

Impact Rate
number · IPM
2400

Impacts per minute, or BPM on hammer drills. Pairs with torque to describe how the tool actually delivers it.

Anvil Retention Type
enum
Hog Ring

Friction ring, hog ring or detent pin. Same model ships in multiple anvil variants under separate MPNs; overhead work dictates the choice.

Tool Weight (EPTA 01/2014)
number · lb
7.4 (with 5.0 Ah)

Only comparable if the basis and the fitted battery are stated. Bare-tool and with-battery weights differ by pounds on high-Ah packs.

Compliance & identifiers

Standards, regulatory data, and the identifiers channels reject you for missing.

Vibration Emission (ah)
number · m/s²
16.8 (K = 1.5)

Declared per EN 62841 with uncertainty K, per operating mode. EHS buyers need it to build hand-arm vibration exposure sheets.

Safety Certification
enum
UL/CSA 62841-2-2

The listing the tool and its battery/charger system are certified to. Required by many plant and public-sector purchasing rules.

The fields that aren't in the schema at all

What most cordless power tools catalogs are missing.

The table above is the schema most catalogs already have. These are the attributes that usually aren't in it — each one surfaced by a signal from the live market rather than by an audit of what's already there. This is what Anglera's Schema Foundry does on a real catalog, in this category.

Supplier signal
+ Max Breakaway (Nut-Busting) Torque

Manufacturer pages publish both figures — DCF961B is rated 1,200 ft-lb fastening and 1,750 ft-lb breakaway. Distributor catalogs carry one field called 'Max Torque' with no basis stated.

Range filters compare one SKU's fastening number against another's breakaway. Tool is specced to loosen seized fasteners, cannot, and comes back.

Competitor signal
+ Anvil Retention Type

The same impact wrench ships as a hog-ring and a detent-pin variant under separate MPNs. Most catalogs hold one record with no anvil field and no way to filter it.

Wrong variant shipped. Detent-pin anvil arrives where the crew needs hog-ring socket retention for overhead work; restock and reorder.

Search signal
+ Vibration Emission (ah) per EN 62841

Declared only in the declaration table of the instruction manual PDF, per mode, with uncertainty K. Buyers searching a catalog for 'vibration m/s2' get zero results.

EHS-driven and public-sector RFQs go unanswered. No way to support a hand-arm vibration exposure assessment from the catalog.

Marketplace signal
+ Battery Watt-Hours and UN Shipping Classification

Marketplace and freight intake ask for Wh, the UN number (UN3481 for cells packed with equipment) and a UN 38.3 test summary. Catalogs carry Ah only.

Listing suppressed at compliance intake. Air freight held pending a Wh figure that has to be recalculated by hand from Ah × nominal voltage.

Search signal
+ Head Length

Buyers search 'compact impact wrench' and 'short head length' against clearance in a machine bay. Overall length is sometimes present; head length rarely is.

Tool does not fit the access it was bought for. Return on a non-defective item, and a filter competitors expose that the catalog cannot.

How Schema Foundry finds these

Messy in, governed out.

The same value, spelled every way industrial MRO suppliers spell it. A filter only works once they agree.

Voltage, Nominal
20V MAX*20 Volt Max18V18 V DC20VM18
18 V DC

DeWalt's own asterisk reads: maximum initial battery voltage is 20 volts, nominal voltage is 18. One pack, two marketing conventions.

Motor Type

Brand motor names wrap a single binary fact. Unnormalized they shatter the facet buyers reach for first into six dead-end values.

Max Fastening Torque

1200 ft-lb

in-lb, ft-lb and Nm arrive in one feed, and 'ft/lb' is a live unit error in real listings. A range slider sorts these silently and wrongly.

Chuck / Drive Size and Type

Keyless Chuck, 1/2 in (13 mm)

Metric and imperial spellings of the same chuck split the facet, and 1/4 in hex quick-change gets filed in the same field as a chuck.

What buyers ask

Every one of these should be answerable from the attributes above. If it isn't, that's a gap.

  • Will this run on the M18 batteries we already have in the crib?
  • Is that the tool only, or does it come with batteries and a charger?
  • Is 20V MAX the same battery as an 18V, or do I need a different pack?
  • How much breakaway torque? Will it crack a seized 1-1/8 in flange nut?
  • Does it have a hog ring anvil or a detent pin?
  • What does it weigh with the 5.0 on it? They're running it overhead all shift.
  • What's the vibration number? I need it for our HAV exposure sheet.
  • What's the head length? I've got about 3-1/2 in of clearance in there.

Cordless Power Tools data, in practice

Is 20V MAX the same as 18V?

Yes. Both describe the same 5-cell lithium-ion pack. 20V is the maximum voltage measured off the charger with no load applied; 18 V is the nominal voltage under load. DeWalt's own disclaimer states it plainly: maximum initial battery voltage measured without a workload is 20 volts, nominal voltage is 18. The identical tools ship marked 18V in markets that require nominal-voltage marketing. Store nominal voltage in the governed field and keep '20V MAX' as a supplier-side synonym and a display token. If both values live in one facet, a buyer filtering 18 V never sees half the catalog, and a voltage range filter reports two populations of the same tool.

Fastening torque or breakaway torque — which should the record carry?

Both, each with its unit and its basis. Fastening torque is what the tool applies driving a fastener down. Breakaway, or nut-busting, torque is what it delivers loosening a seized one, and it is normally the higher of the two: a DeWalt DCF961B is rated 1,200 ft-lb fastening and 1,750 ft-lb breakaway. Manufacturers publish both figures. Catalogs typically flatten them into one field labelled 'Max Torque' with no qualifier, so a side-by-side of two SKUs may quietly be comparing a fastening number against a breakaway number. Maintenance buyers spec on breakaway. Assembly buyers spec on fastening. One field cannot serve both.

Where do the vibration, noise and weight numbers actually come from?

The declaration tables in the instruction manual, not the marketing page. Under EN/IEC 62841 the tool declares a vibration total value (ah, triaxial vector sum) with uncertainty K in m/s², and noise as LpA and LwA in dB(A) with K — and it declares them per operating mode, so one combination tool can carry three different ah values. Weight is a separate standard: EPTA-Procedure 01/2014, and manufacturers state which battery is fitted when they quote it. Any of these lifted out of the PDF without its mode, its uncertainty, or its battery is not comparable to the next brand's figure, which is the whole reason the standard exists.

Why does one tool exist under five part numbers?

Configuration and variant explosion. A single impact wrench ships as a bare tool, as a kit with two 5.0 Ah packs, as a kit with two 12.0 Ah HD packs, and in hog-ring and detent-pin anvil versions — each with its own MPN and GTIN and all with the same headline torque. Milwaukee's -20 (tool only) and -22 (kit) suffix pattern is the standard case. If Sold As, Batteries Included, Battery Capacity and Anvil Retention Type are not modeled as real attributes, those SKUs collapse into one record the buyer cannot choose between, and the spread between the bare tool and the kit reads on the page as a pricing error.
