Centre drill DIN 333 Form B, 1.25 mm HSS (TECWERK) — centre drill with protective countersink and 5 mm shank

The centre drill DIN 333 Form B, 1.25 mm HSS with protective countersink provides an accurate pilot and countersink in a compact format, intended for general machining tasks and the production of centre holes to DIN 332 Sheet 1 Form B

• HSS construction for excellent wear resistance
• DIN 333 Form B for standard-compliant centring
• Integrated protective countersink prevents burrs
• 5 mm shank for secure clamping in standard holders

Consistent centring and reduced rework thanks to robust HSS design

The HSS composition ensures a balanced combination of toughness and edge retention, which translates into consistent centring and fewer reworked components in both one-off and serial production. With a nominal diameter of 1.25 mm and an overall length of 40 mm, this centre cutting tool provides a compact footprint ideal for tight setups. The right-hand cutting geometry produces predictable chip formation, while the modest overall dimensions reduce the risk of runout when clamped in a suitable holder. This results in lower scrap rates and a steadier machining cycle.

Built to standards: reliable fit and predictable performance

Conforming to DIN 333, Form B, the tool assures compatibility with established centring practices and fixtures; the included protective countersink with a 60/120° profile helps to form a clean entry that minimises burrs and edge fractures. For steel conditions up to 800 N a recommended feed of 0.02 mm/rev is indicated, delivering a reliable compromise between process speed and surface integrity. The 5 mm shank ensures easy insertion into standard drill chucks or collets, making the tool a dependable choice for workshops aiming to streamline inventory without sacrificing interchangeability.

Practical advantages for everyday workshop use

Designed for general-purpose application, this centre drill offers practicality where repeatability matters most: accurate pilot holes reduce cycle-to-cycle variability, and the protective countersink reduces the need for secondary deburring. The compact design is particularly suited to turning centres and small milling fixtures where space is limited and quick changeover is required. The result is a reduction in setup time and an improvement in first-time-right rates, which benefits both small craft shops and volume-oriented production lines.

FAQ

What materials can be machined with this centre drill? The TECWERK centre drill is made of HSS and is suitable for general machining tasks; for steels up to 800 N a feed of 0.02 mm/rev is recommended to balance tool life and surface quality.

What is the shank size and how should it be clamped? The tool has a 5 mm shank and is compatible with standard 5 mm drill chucks, collets or shrink-fit holders designed for that diameter; refer to SKU 2000861629NW for exact specification.

What benefit does the protective countersink provide? The integrated protective countersink (60/120°) reduces burr formation at the entry, improves centring reliability and lowers the need for subsequent deburring when producing centre holes.

Which standards does this tool comply with? This centre drill is manufactured to DIN 333 Form B and is intended for producing centre holes in accordance with DIN 332 Sheet 1 Form B, ensuring standardised geometry and interchangeability.

What cutting direction and feed rates are recommended? The tool is right-hand cutting; for steel up to 800 N a feed of 0.02 mm per revolution is advised to achieve stable cutting and consistent centring quality.
