Overview

The Snappy 1/8 Drill Adaptor #30 takes a standard round drill bit and holds it in a 1/4 hex power bit shank, so the bit works in quick change chucks, impact drivers and any tool built for 1/4 hex accessories. A collet compresses around the bit to hold it securely, and the adaptor is heat treated for durability.

It is a small part that solves a common problem on site: most drills and drivers today take hex shank accessories, yet the drill bits you already own are round shank. This adaptor bridges the two, so the 1/8in bits in your kit work in the impact driver without buying a second set of hex shank drills.

What You Need to Complete the Job

Pair the adaptor with a P&N quickbit hex shank drill or a P&N step drill for a full hex shank kit, and browse the General Hand Tools range for more. Keep the collet clean and free of swarf so it grips the bit squarely, and carry a spare adaptor if you do a lot of production drilling.

Frequently Asked Questions

What does this adaptor do?

It holds a round 1/8in drill bit in a 1/4 hex shank so the bit can be used in impact drivers, quick change chucks and other hex drive tools. The collet compresses around the bit to grip it firmly, so standard bits work where normally only hex shank accessories fit.

What size bits does it hold?

The adaptor is rated for 1/8in drills and holds the rated size down to 1/64 inch smaller. That covers the common small HSS bits used for pilot holes and sheet metal work, and the grip range means a slightly worn bit still sits firmly.

Why use a drill adaptor?

It lets you use the round shank bits you already own in a hex drive tool, so there is no need to buy a second set of hex shank drills. Swapping between drilling and driving becomes a matter of seconds, which is what quick change systems are for.
