Chuck trick stops skinny drill bit deflection
When making detailed scrollsawn patterns, I often use drill bits 1⁄16" or smaller in tight areas.
When making detailed scrollsawn patterns, I often use drill bits 1⁄16 " or smaller in tight areas. But those tiny bits want to deflect—moving off target—no matter how slowly I feed the bit.
To stop that deflection, insert the drill bit into the chuck so only 1⁄4 " of the bit shows. Drill the holes about 1⁄8 " deep, and then extend the bit from the chuck at full length and drill the holes again. The first hole acts as a guide to keep the bit perfectly on track.
