Where this product is used

Star-M auger bits are used by carpenters, joiners, cabinet makers, and timber frame contractors requiring precision holes in timber.

Selecting the right option

Select the Star-M series based on the material and bore depth required: 4S for standard softwood applications; 4L for extended-reach framing and through-boring; 8M and 8L series for hardwood where the reinforced, hardened geometry maintains performance. Match the diameter to the fastener, dowel, or service requirement. Packs of 50 offer best value for production environments.
