Set of 6 countersink bits, wood countersink bits with depth stop, 6.35 mm (1/4") hexagonal shank, HSS-M2 high-speed steel, precision drilling for woodworking

【Dimensions】This 6-piece countersink bit set includes 4 different sizes: 2.8 x 8 mm, 3.2 x 8 mm, 3.5 x 10 mm, and 4 x 10 mm (all with a 9.5 mm countersink and a 6.35 mm hex shank), as well as a hex key.

【Adjustable Depth】The wood countersink bits with a depth stop prevent over-drilling, improving work efficiency. The countersink length is adjustable via a cross-reference scale, allowing you to adapt the drilling length to different screw lengths. The increased-friction depth control ring effectively reduces surface damage. 【Fast Chip Removal】The helical edge of the wood countersink bits quickly removes chips from the hole, preventing debris buildup and clogging.

【Versatile Use】This countersink bit set is suitable for natural wood, particleboard, fiberboard, plywood, and MDF. Note: For optimal results and smooth edges, it is recommended to use the countersink bits at a slow speed of approximately 200 RPM. Not recommended for metal and sheet steel.
