42020 – 5/16″ Drill Bit Adapter

Snappy drill bit adapters utilize a collet to adapt standard round drill bits to a 1/4″ hex power bit shank to be used in quick change chucks and other tools designed to accept a 1/4″ hex shank, like impact drivers. Heat treated to a specific hardness to provide durability, while still maintaining the collets ability to compress around the drill bit. Securely holds a round drill bit of the rated size to 1/64″ smaller.

• Drive Shank:  1/4″ Hex Power Bit Shank
• Recommended Drill Size: 5/16″ (Twist drill not included with individual drill be adapters)

Always use a Hex Shank Socket (Part #42001) to protect the shank from damage when replacing twist drills or Use the Bench Mount Shank Wrench (Part #42881) for easier bit changes!
