HW countersink for 4 flutes drills D16 d4 RH

HM 45° counterbore for drills with four flutes mounted on shank d4 – precision bevelling and high durability

Index: BBC2.040.016.01R

Industrial counterbore with sintered carbide (HM) blades from the BBC2 line, designed for mounting on the shank of drills equipped with four chip flutes, used in multi-spindle drilling machines and CNC machining centres. The tool allows for simultaneous drilling of a hole and bevelling its edge at an angle of 45° in one working cycle. The high-quality sintered carbide blades ensure clean edge finishing and long service life. The dedicated design and stable fastening with a clamping screw on the tool's shank allow for precise setting of the bevelling depth.

Design advantages and technical properties:

• Fit for drills with four flutes: The dedicated profiling of the counterbore ensures perfect compatibility with drills featuring a four-flute design, providing a hassle-free chip exit and stable bevelling process.
• Sintered carbide (HM) 45° blades: Precisely ground cutting edges made of carbide provide a high standard of bevelling, no tearing, and high operational durability.
• Mounting on drill shank: The design adapted for mounting on the tool's shank ensures stability and repeatability of the counterbore positioning.
• Secure fastening with clamping screw: The clamping fastening system allows smooth position adjustment and quick change of bevelling depth.
• Combination of two operations in one pass: Simultaneous drilling and counterboring significantly reduces processing time and increases production process efficiency.

Purpose and scope of application:

The tool is intended for bevelling at an angle of 45° around holes for screws, furniture connections, and screw heads.

It performs excellently in machining materials such as solid wood, wood-based materials, MDF, HDF, and laminated boards.
