TECWERK conical countersink, 120° – 20.5 mm, HSS, 3 flutes, 10 mm shank

A TECWERK conical countersink for precise deburring, countersinking and recessing in metals, suited to workshop and industrial use.

• HSS, 3-flute geometry for smooth cut
• 120° conical angle for standard countersinking
• 20.5 mm cutting diameter for wide countersink heads
• 10 mm cylindrical shank for secure toolholding

Faster, cleaner countersinking with reduced rework

The HSS construction and 3 flutes deliver a balanced combination of toughness and chip evacuation, ensuring smoother cuts and fewer burrs. The 120° point angle matches common fastener profiles, so the countersink cutter produces consistent seating for screws and rivets. With a 20.5 mm cutting diameter, the tool removes material efficiently over a wider contact area, reducing the number of passes required and therefore cycle time. These measurable advantages support a more economical production flow through less rework and predictable results.

Stable clamping and controlled feed for longer tool life

A 10 mm shank and cylindrical shank design provide rigid toolholding in standard collets and chucks, limiting runout and vibration during operation. Classified as Form C with right-hand cutting, the geometry is optimised for conventional machining directions. For steel work, the recommended feed is 0.2 mm/rev, which, together with the note that best results are achieved at low cutting speed, helps to avoid premature wear and maintain edge integrity. This technical setup translates into longer service intervals and steady cutting performance under repeated use.

Versatile application, straightforward procurement and trusted supply

The countersink cutter is built for burr-free countersinking and deburring across a range of materials, with particular effectiveness in steel and non-ferrous alloys. Its robust design supports operations such as chamfering mating faces and preparing bores for flush fastener seating, making it a reliable choice for workshops and light production environments. For supply and technical clarification, Metav Werkzeuge acts as a quality filter and distribution partner, offering logistic reliability from Emmerich and expert guidance to ensure the tool matches the production needs.

FAQ

What materials is this countersink suitable for?
The TECWERK conical countersink is suitable for steel and non‑ferrous metals; its HSS construction and 3‑flute geometry support clean deburring and countersinking in these materials.

Which shank size is required for secure clamping?
A 10 mm cylindrical shank is specified for the tool, so standard 10 mm collets and chucks are recommended to ensure stable clamping and minimal runout.

What cutting angle does the tool use and why is it important?
The tool has a 120° conical angle, which is a common standard for creating correct screw and rivet seating and helps to achieve uniform countersink profiles.

How should feed and speed be configured for steel?
For steel, use the recommended feed of 0.2 mm/rev and favour lower cutting speeds to preserve edge life and reduce burr formation when using this countersink.

Can this countersink be used for deburring as well as countersinking?
Yes, the 3‑flute HSS geometry and conical design make the cutter effective for both countersinking and burr‑free deburring applications.
