RUKO KES-DIN335-HSS-TiN-90°-Ø23,0mm verzinkboor

Machinists and metalworkers rely on the RUKO KES-DIN335-HSS-TiN-90°-Ø23.0mm countersink bit for precise deburring, chamfering, and countersinking in steel, cast iron, non-ferrous metals, and plastics. Its 90° cutting angle and 23.0 mm cutting diameter produce clean, consistent chamfers for flat-head screws and rivets.

Key specifications

• Tool Type: Countersink
• Standard: DIN 335 Form C
• Material: High-Speed Steel (HSS)
• Coating: Titanium Nitride (TiN)
• Cutting Angle: 90°
• Cutting Diameter (D3): 23.0 mm
• Shank Diameter (D1): 10.0 mm
• Overall Length (L1): 67 mm
• Number of Flutes: 3
• Shank Type: Cylindrical Shank
• Cutting Direction: Right-hand cut
• Manufacturing Process: Ground Profile
• Tolerance (Shank): h8
• Series: KES

Why choose it

The TiN coating increases surface hardness and reduces friction, extending tool life and improving chip flow. The ground profile ensures accurate cutting edges, while the cylindrical shank with h8 tolerance provides secure clamping in standard collets or chucks.

Ideal use cases

• Deburring drilled holes in steel and cast iron
• Chamfering edges for screw seating in non-ferrous metals
• Countersinking flat-head screws in plastic components

Good to know

This countersink is part of the RUKO KES series, engineered for consistent performance in workshop and production environments. It is suitable for use with stationary drilling machines and hand drills when proper speed and feed are applied.
