Centre Drill DIN 333 Form R, 4.0 mm (HSS) — TECWERK

Centre Drill DIN 333 Form R for reliable preparation of lathe centres and pre‑drilled pilot points in general workshop and production environments

High-speed steel (HSS) construction
DIN 333 Form R geometry
60° countersink angle for standard centres
0.03 mm/rev feed up to 800 N in steel

Accuracy that reduces rework and machine time

The DIN 333 Form R geometry is designed to produce repeatable centre holes with a defined radius, improving concentricity for subsequent turning or drilling operations. A consistent centre form minimises runout and reduces the need for corrective machining, which in turn shortens cycle times and lowers scrap rates. Conformity to recognised standards ensures interchangeability of results across fixtures and machines, helping to stabilise process capability in small-batch and serial production alike.

Robust design for everyday workshop use

Made from HSS, this centre drill combines toughness with the necessary hardness to resist premature wear in standard workshop materials. The right-hand cutting geometry provides clean entry and predictable chip flow, while the 10 mm shank fits common tool holders and the 56 mm overall length offers easy handling and stable clamping. The execution is supplied without protective countersink, which means the tool is dedicated to producing the correct centre form without an additional recess; this simplicity supports straightforward indexing and repeatable seating of centres.

Predictable performance for process planning

A 60° countersink produces the standard conical seat required by DIN 332 Blatt 1 Form R, so parts are ready for accurate lathe mounting and tailstock seating. Practical machining data such as a recommended feed of 0.03 mm/rev in steel up to 800 N provides planners with a clear starting point for cutting parameters and tool life estimation. The combination of standard geometry and known cutting parameters enables reliable cycle-time calculation and easier tool inventory management, contributing directly to smoother production flows.

FAQ

What is the main application of this centre drill?
The centre drill is intended for preparing accurate centre holes and pilot points prior to turning and drilling operations; the Centre Drill DIN 333 Form R by TECWERK produces a standard centre form for reliable workpiece mounting.

Which toolholders are compatible with the shank?
The 10 mm shank fits common collets and chuck adaptors used in general workshop and production toolholding systems.

What cutting data should be used for steels?
A practical starting point is the recommended feed of 0.03 mm/rev for steels up to 800 N; this value helps to achieve good tool life and consistent hole form.

Why is the tool supplied without a protective countersink?
The execution without protective countersink means the drill focuses on forming the accurate centre radius required by DIN 332 Blatt 1 Form R, eliminating a secondary recess and simplifying seating in tailstocks.

How is the product supplied (packaging)?
The article is supplied in a packaging unit corresponding to established workshop assortment sizes.
