Through‑hole countersink 1–4 mm, 90° HSS‑Co (TECWERK) — through‑hole design for secure chip evacuation and clean deburring

Through‑hole countersink 1–4 mm, 90° HSS‑Co for burr‑free chamfers and smooth deburring in workshop and production environments

• HSS‑Co cutting material for high wear resistance
• 90° countersink angle for precise chamfers
• Shank Ø 6.35 mm for standard tool holders

Consistently precise chamfers that reduce rework

The HSS‑Co construction delivers high edge stability and longevity under intermittent loads, producing clean chamfers without tearing. The shearing geometry ensures a controlled cut, so each pass removes burrs rather than crushing them; this translates into fewer secondary operations and a steadier production flow. Using a countersink with defined 90° geometry provides repeatable results when preparing holes for fasteners or creating neat edge finishes.

Secure chip control for uninterrupted machining

A defining benefit of the design is its through‑hole chip evacuation: chips exit through the centre rather than building up in the flute, which prevents clogging and the risk of the tool seizing in the workpiece. That reliable chip evacuation supports safer, more efficient operation on lathes and drill presses, reduces downtime and protects component surfaces from damage caused by recut swarf.

Versatile for common workshop materials with clear feed guidance

Engineered for work on steel, cast iron and non‑ferrous metals, the tool delivers best results at lower cutting speeds to preserve edge life and surface quality. For steel applications the recommended feed is around 0.07 mm/rev under cutting forces up to 500 N, which balances chip formation and surface finish. The countersink is also suitable for light alloys where a deliberate, lower speed approach avoids smearing and achieves a sharp edge.

Compact dimensions for easy integration into toolsets

The combination of a slim shank Ø 6.35 mm and an overall length 45 mm makes the cutter compatible with common collet chucks and quick‑change holders, simplifying setup and replacement. The compact profile supports access in tight fixturing and handheld machines while maintaining stability. The unit is supplied for single‑item workshop stocking and is optimised for simple storage and fast replenishment.

FAQ

Which materials is this countersink suitable for?
The TECWERK through‑hole countersink is suitable for steel, cast iron, non‑ferrous and light metals, offering burr‑free chamfers on these materials.

What feeding rate and cutting conditions are recommended?
For steel, aim for a feed of around 0.07 mm/rev under cutting forces up to 500 N and prefer lower cutting speeds to extend tool life and improve finish.

What are the shank and overall dimensions?
The tool has a shank diameter of 6.35 mm and an overall length of 45 mm, making it compatible with standard collets and holders.

How does the through‑hole design affect performance?
The through‑hole allows chips to escape via the centre, which prevents clogging, reduces the chance of jamming and produces a cleaner surface without rework.

Is the cutter good for deburring as well as countersinking?
Yes, the shearing geometry and HSS‑Co material enable clean deburring as well as accurate countersinking for assembly preparations.
