Metallics AL112 Wood Bit Ship Auger Dia 1-1/2" 18" Hex Shank (1 pc)

That is exactly the use case. A ship auger like the AL112 has a long single flute body that pulls itself through wood and clears chips out of a deep hole, which is what an electrician wants when drilling stud bays and plates for conduit, MC, or NM runs. The 1-1/2 inch bore gives clearance for larger raceway or a bundle of cable. For shallow holes in a single 1-1/2 inch stud, a shorter auger or a selfeed bit is quicker; the 18 inch length earns its keep when you are drilling several members at once or working at an angle through a bay.

One bit per order, supplied in a pouch rather than loose or in a bulk box. Order one per size you need; there is a single model on offer, AL112, the 1-1/2 inch by 18 inch.

Treat it as a wood bit. It is specified as a wood bit ship auger, so it is ground for clean boring in solid timber and framing. Hitting nails, screws, or nail plates will chip the cutting lip; for demolition or reclaimed stock where metal is likely, use a nail-eater style auger instead.

Metallics part number AL112, described as a wood bit ship auger, 1-1/2 inch diameter, 18 inch, hex shank. Use AL112 when cross-referencing with a distributor.
