TECWERK 75° Countersink Ø 20.5 mm — HSS, 3-flute, Shank Ø 10 mm

TECWERK 75° Countersink Ø 20.5 mm HSS Z3 with 10 mm shank is a precision countersinking tool designed for smooth deburring, spot-facing and reliable chamfering across a range of common workshop materials

• Countersink Ø 20.5 mm, 75° angle
• Solid HSS construction, long tool life
• Three cutting edges for smooth deburring
• 10 mm cylindrical shank, machine-ready

Accurate chamfers and reduced rework for production environments

The combination of high-speed steel and a 75° chamfer angle delivers consistent chamfers and spot faces with minimal risk of burring or material tearing. The Ø 20.5 mm cutting diameter allows for defined countersink sizes, while the three flutes ensure even material removal and a fine surface finish. These characteristics translate into fewer secondary operations, less rework and more predictable cycle times, which supports efficient throughput on the shop floor.

Robust design for reliable machine integration

A cylindrical shank with shank Ø 10 mm provides secure clamping in standard tool holders and drill chucks, making the tool suitable for both bench machines and CNC setups that accept straight shanks. The tool is right-hand cutting and manufactured to Form C geometry, delivering steady cutting action. For steel under moderate load the recommended longitudinal feed is 0.16 mm/rev, a value that balances surface quality and tool life while keeping forces within typical machine capabilities.

Versatile application across a range of materials

The geometry and material of the tool are optimised for burr- and ratter-free countersinking and deburring in steel, cast components and non-ferrous or light metals, producing clean, repeatable chamfers. Best results are achieved at low cutting speeds, where the HSS composition maintains edge integrity and reduces the chance of thermal softening. The result is a dependable finishing operation that contributes to higher perceived product quality and improved assembly fit.

FAQ

What materials can this countersink machine effectively work with?
The TECWERK 75° countersink (SKU 2000865136NW) is suitable for steel, cast components and non‑ferrous or light metals, offering clean chamfers and effective deburring when used at lower cutting speeds.

What is the shank size and how is it held?
This countersink features a 10 mm cylindrical shank, intended for secure clamping in standard drill chucks and straight-shank tool holders compatible with the TECWERK countersink.

How many cutting edges does the tool have and what is the benefit?
The tool has three cutting edges, which promote balanced cutting action and a smooth surface finish, reducing vibration and the need for secondary finishing of the countersunk hole.

What feed rate should be used for steel applications?
For steel with moderate strength the recommended feed is 0.16 mm per revolution, as specified for the TECWERK countersink to achieve a balance between finish quality and tool life.

Is the tool suitable for production use on machines?
Yes. The solid HSS construction, cylindrical shank and three-flute geometry of the TECWERK countersink make it appropriate for production environments that require consistent countersinking and deburring performance.
