TECWERK centre drill DIN 333 Form R Ø 1.60 mm (HSS) — 60° countersink

The TECWERK centre drill DIN 333 Form R Ø 1.60 mm (HSS) is designed for fast, accurate production of standard centre holes with a radius tip, suitable for general workshop and light industrial applications.

• HSS construction for durability and wear resistance
• DIN 333 Form R geometry with radius tip
• 60° countersink angle for standard centre holes
• 4 mm shank for secure clamping

Reliable seating through radius-tip geometry

The radius tip (Form R) follows the requirements of DIN 332 part 1, producing a controlled centre indentation that reduces run-out and facilitates subsequent drilling or turning. The radius-shaped point prevents the brittle fractures sometimes seen with sharp-point centre drills and contributes to consistent workpiece seating, which in turn lowers scrap rates and reduces the need for rework. This geometry is particularly helpful when repeatability and alignment are essential in small-batch production or maintenance tasks.

Robust HSS body for everyday machining

Constructed from HSS, the tool provides a balance between toughness and hardness that is well suited to general-purpose metalworking. The high-speed steel composition gives resistance to heat and wear during intermittent use, while the right-hand cutting orientation matches common machine spindle directions. A compact 4 mm shank ensures compatibility with small chucks and collets, offering secure clamping for both hand-fed and machine operations. The result is a dependable centre drill that keeps tools and setups consistent across routine processes.

Practical machining parameters and compatibility

The centre drill is specified as Ø 1.60 mm with an overall length of 35.5 mm and a 60° countersink angle, matching standard centre-hole profiles. It is supplied without protective countersink, so it creates the radius-profile centre only, rather than a stepped pilot. For steel applications up to 800 N, a feed of 0.02 mm/rev is indicated; this recommendation supports efficient material removal while maintaining tip integrity. These clear parameters make process planning straightforward and reduce trial-and-error on the shop floor.

Efficiency and workshop integration

Compact tooling like this centre drill supports lean workflows: shorter setup times, fewer tool changes and consistent centre positions for downstream operations. The compliance with DIN 333 ensures interchangeability with established procedures and jigs, simplifying procurement and inventory management. Combined with Metav’s availability and advisory support, the bit provides a practical route to improve precision without overcomplicating the tooling portfolio.

FAQ

Is this centre drill suitable for steel work?
The TECWERK centre drill DIN 333 Form R in HSS is intended for general steel applications; the recommended feed in steel up to 800 N is 0.02 mm/rev.

Can the tool be used in standard holders and chucks?
Yes, the 4 mm shank allows secure clamping in chucks and collets that accept that diameter, making the centre drill compatible with many small spindles and bench machines.

Why choose the Form R radius tip instead of a sharp point?
The radius tip reduces the risk of tip fracture and creates a consistent seat for subsequent drills or centres, improving repeatability and reducing rework.

What size of centre hole does the 60° angle produce?
The 60° countersink angle produces a standard centre profile in accordance with DIN 332 part 1 Form R, suitable for conventional centre seating and turning operations.

Is this a left- or right-hand cutting tool?
The drill is right-hand cutting, matching common spindle rotation and standard tool orientations.
