Countersink 120° D 10.4 mm HSS, 3‑flute, 6 mm shank – TECWERK

A Countersink 120° D 10.4 mm HSS designed for precise, burr‑free countersinking, deburring and seating in steel, cast and non‑ferrous metals

• HSS, 3‑flute design for smooth cutting
• 120° countersink angle for standard seating
• 6 mm cylindrical shank for secure clamping
• Burr‑free countersinking in steel and non‑ferrous metals

High‑precision performance for production tasks

The HSS material and 3‑flute geometry combine to provide stable cutting and a clean finish when countersinking and deburring. The tool’s Form C geometry reduces chatter, which results in a more consistent seat and fewer rework cycles. Recommended for lower cutting speeds, the design focuses on delivering reliable results when machining thicker sections or tougher alloys, supporting continuous operation in small workshops and industrial settings alike.

Material compatibility and optimised cutting data

Engineered for multi‑material use, the countersink performs well in steel, cast components and a range of non‑ferrous and light metals. The specified feed capability in steel is 0.12 mm per revolution at up to 500 N, which balances tool life with surface quality. The tool is right‑hand cutting and achieves best outcomes when applied with conservative spindle speeds and steady feed—this approach reduces heat generation and extends service life while maintaining the required seating accuracy.

Workshop advantages: efficiency and ease of use

A 6 mm cylindrical shank permits straightforward mounting in standard chucks and collets, reducing set‑up time and making the tool suitable for batch work and occasional maintenance tasks. The three‑flute profile evacuates chips efficiently and helps to avoid clogging during plunging operations, which supports faster throughput and less stoppage for cleaning. These practical features translate into measurable gains in daily productivity and lower scrap rates.

Design details that matter for consistent assembly

The 120° angle corresponds to common countersink standards for fastener seating, enabling correct screw or rivet fit without additional finishing. The tool’s right‑hand cutting action and burr‑control geometry are specifically aimed at producing a clean chamfer and a reliable mating surface for downstream assembly. For applications requiring the highest precision, the profile of the tool minimises deviation and contributes to reproducible joint quality across multiple parts.
