Centre drill DIN 333 Form B, Ø 1.25 mm — HSS with protective countersink (TECWERK)

Centre drill DIN 333 Form B, Ø 1.25 mm — HSS with protective countersink (TECWERK) is a compact pilot cutter designed for producing accurate centre holes to DIN 332 Blatt 1 Form B, with an integrated protective countersink for cleaner seating and reduced burr formation

• HSS DIN 333 Form B geometry
• Integrated protective countersink
• Dual 60/120° centring angles
• Right‑hand cutting, stable pilot formation

Precision starts with stable centring and reduced drill wander

A correctly formed pilot hole is the basis for every accurate drilling operation. The centre drill conforms to DIN 333 geometry and creates a defined seat for subsequent twist drills, preventing walking and misalignment on the workpiece. The integrated protective countersink produces a controlled chamfer around the centre hole, which improves tool seating and reduces burrs during turning or drilling operations. This results in fewer rejects and shorter rework times, helping maintain a steady production flow.

Geometry and material for consistent machining performance

Manufactured from HSS, the cutter combines toughness and wear resistance suitable for general workshop use. The combined 60/120° centring angles deliver a precise initial tip for accurate positioning and a broader flank for robust support during feed. The tool is designed for standard right‑hand rotation (right‑hand cutting) and specifies a guideline feed in steel (up to 800 N) of 0.02 mm/rev, which helps set realistic machining parameters and avoids overfeeding that could shorten tool life. These measurable values support process reliability on conventional lathes and drill presses.

Integrates into existing machining workflows with minimal setup

The pilot cutter is intended as a preparatory operation before conventional twist drills, reducing the risk of drill walking and improving hole concentricity. Conformity with recognised standards (centre holes to DIN 332 Blatt 1 Form B) ensures compatibility with established jigs and fixtures and simplifies process documentation. For workshops seeking to streamline setup times, the tool’s simple geometry means quick replacement and predictable seating, which supports efficient cycle planning and shorter machine downtime.

Durable handling for repeated shopfloor use

Designed for routine use, the tool’s solid construction and built‑in countersink minimise edge breakage and facilitate cleaner chip evacuation at low to moderate cutting speeds. The compact design makes the cutter easy to store and exchange without time-consuming regrinds. For procurement planning, the item is supplied in a small pack, offering convenient stock rotation for repair shops and small series production. The consistent performance also contributes to lower total process costs through reduced scrap and less tool-related disturbance.

FAQ

What is the main function of this centre drill?
The TECWERK centre drill is used to create precise pilot holes and a protective countersink so that subsequent twist drills start accurately and do not walk.

Which materials can be machined with this cutter?
The cutter’s HSS construction is suitable for a wide range of common workshop materials; the specified feed value in steel up to 800 N (0.02 mm/rev) provides a guideline for routine steel operations.

How do the 60/120° angles affect drilling?
The combined 60/120° geometry provides an accurate initial tip for positioning and a stable flank for support, improving hole concentricity and reducing the risk of tip breakage.

Is the item compatible with standard drill chucks and lathes?
Yes, the centre drill follows DIN 333 geometry and is compatible with conventional chucks and fixtures used for centre‑drilling operations; the SKU 2000861629NW identifies this specific item.

What does the protective countersink provide?
The integrated countersink forms a clean chamfer around the centre hole, improving seating for subsequent tools and reducing burr formation during machining.
