Japanese Drill Bit with Countersink - Chamfer

A quick way to align screw heads with the surface of the material being worked on. The special drill bit creates a pilot hole for standard screws. The chamfering tool then widens and deepens the hole, making it easier to sink the screw head into the wood.

Specifications:

• Drill bit diameter (D1): 4mm
• Chamfering diameter (D2): 12mm
• Maximum working length of the drill bit: 20mm
• Maximum chamfering depth: 20mm
