TECWERK Countersink DIN 335 C — 90° Ø 12.4 mm, HSS‑Co, 3‑flute

A TECWERK Countersink DIN 335 C engineered for precision countersinking and deburring of holes in steel, cast iron and non‑ferrous metals in workshop and production environments.

DIN 335 C countersink, 90° angle
Three flutes for vibration-free cutting
HSS‑Co for stainless and heat-resistant steels
Cylindrical shank for secure toolholding

Accurate countersinking for dependable mechanical joins

The DIN 335 C geometry with a 90° tip angle ensures consistent chamfer dimensions for reliable seating of fasteners. The design supports repeatable preparation of holes so that assemblies meet specified tolerances without rework. Where hole concentricity and chamfer uniformity are critical, this countersink delivers predictable results that simplify downstream assembly operations.

Long tool life and cutting performance in demanding materials

Made from HSS‑Co, the tool is formulated to withstand elevated temperatures and abrasive conditions encountered when working with stainless and heat‑resistant steels. The cobalt content increases hot hardness and wear resistance, which translates into longer intervals between tool changes and reduced process downtime. For machinists requiring durable cutting edges in mixed‑material shops, the material choice balances performance and longevity.

Smooth, chatter‑free operation that protects workpiece finish

The three‑flute configuration provides a balanced cutting action that reduces vibration and prevents the typical chatter associated with single‑cut countersinks. A rattle‑free cut results in cleaner hole edges and minimised burr formation, lowering the need for secondary finishing. The cylindrical shank ensures reliable clamping in standard toolholders and drill chucks, making the tool simple to integrate into existing workflows.

Practical feed data and application guidance

Rated feed guidance in steel under cutting forces up to 500 N is 0.14 mm/rev, offering a practical baseline for setting feed rates in production. The tool is suitable for both countersinking and deburring tasks across steel, cast iron and non‑ferrous metals, enabling a single cutter to serve multiple applications and reducing tooling complexity on the shop floor. Selection of appropriate spindle speed and feed, in line with material and machine capability, ensures optimal surface quality and tool life.

FAQ

What materials can be processed with this countersink?
The countersink is suitable for steel, cast iron and non‑ferrous metals; the HSS‑Co grade extends capability to stainless and heat‑resistant steels.

Is the tool compatible with standard toolholders and drill chucks?
Yes, the cylindrical shank is designed for secure clamping in common toolholders and drill chucks used in workshops and production.

What makes the three‑flute design advantageous?
The three‑flute geometry produces a rattle‑free cut with reduced vibration, yielding cleaner chamfers and less burr formation compared with fewer‑flute designs.

Which standard does the geometry conform to?
The geometry follows DIN 335 C, providing a standardised 90° countersink profile for consistent chamfer dimensions.

What feed rate is recommended for steel applications?
A practical feed guideline for steel under cutting forces up to 500 N is 0.14 mm/rev, suitable as a baseline when setting feeds in production.
