The Bosch HSS Countersink Bits with hex shank (model 2608596408) are high-speed steel countersinks designed for smooth countersinking of screws and deburring of holes in metals and other tough materials. The ground HSS cutting surface and three 90° cutting edges provide consistent, chatter-free results and produce minimal burrs. The hexagonal shank ensures high power transfer and secure grip in chucks and impact drivers. Manufactured to DIN 335, these countersink bits are suitable for work in non-ferrous metals, steel and cast iron; best results are achieved at low cutting speeds.

Advantages

The hex shank offers secure engagement and improved torque transmission for flush countersinking, while the HSS construction delivers wear resistance and longer life compared with standard carbon steels. Three 90° cutting edges produce even cutting action with reduced burr formation and low vibration. Compliance with DIN 335 ensures dimensional and performance consistency across applications.

Suitable for

• Countersinking screw heads in non-ferrous metals
• Deburring and chamfering holes in steel and cast iron
• Use with cordless impact drivers and drills
• General metalworking and fitting tasks

How to use

Secure the countersink bit in a compatible drill or impact driver with a hex chuck or bit holder. Select a low cutting speed for best results and steady feed to avoid overheating. Position the bit at the required hole or pilot and apply consistent pressure while allowing the bit to cut without forcing. Retract periodically to clear chips and check the countersink depth against the screw head for a flush finish.

Recommendations

For longest tool life and optimal finish, use low cutting speeds, ensure the workpiece is securely clamped, and clear chips frequently. Choose appropriate personal protective equipment, such as eye protection, when working with metal chips.
