Industrial assembly
For equipment panels and workshop assemblies, pair the correct screwdriver bit with the fastener. Start with a low clutch setting and increase only as the joint requires; a torque headline is not a screw-tightening setting.

Workshop drilling
Use a material-specific bit whose shank fits the chuck. Chuck capacity describes the clamped shank, not the maximum hole diameter in every material.
Add hammer-drilling choice
For suitable masonry work, select a masonry bit and the correct hammer mode. For reinforced concrete or sustained heavy drilling, evaluate the rotary-hammer category separately.
The details behind the selection.
The catalog configuration below is a reference, not the only battery option for this model. Request another capacity in the configuration form; the accepted order specification determines the supplied pack and quotation.

Turn PT-21 into your assortment.
Specify the tool, battery quantity, charger plug and accessory pack together. Kit choices below describe your request; they are not a fixed packing list.
Catalog cell specification: 1500 mAh × 10 cells
The mAh value specifies individual cells. Complete-pack capacity depends on the cell arrangement; battery compatibility also requires the correct interface, electronics and charger.
Specify confidently.
Is chuck size the maximum drilling diameter?
No. Chuck capacity is the range of bit shanks it can hold. Hole capacity also depends on material, bit design and operating conditions; do not use chuck size as a drilling-capacity claim.
How should I select between these models?
Start with hammer drilling, then compare the chuck, motor, tool weight where listed and kit format. Use the comparison above to build a shortlist with a distinct role for each SKU.
Are batteries interchangeable across the range?
Match the exact tool interface, electrical specification and supported charger. A shared voltage label or similar cell count does not establish compatibility.
What should be included in an OEM brief?
Specify the model code, target market, quantity, logo placement, approved colour, packaging language, kit contents and acceptance requirements. Review OEM Solutions for the project scope.
Does the displayed kit include accessories?
Photographs show catalog configurations. Your order packing list defines included batteries, charger, case and bits. Accessories and destination-market charger are selected in the inquiry.
