3.15mm Centre Drill DIN 333 Form B With Countersink 60/120° Right-Hand HSS - TECWERK

Thanks to its HSS construction, DIN 333 Form B geometry and integrated protective countersink, this centre drill delivers reliable, repeatable centring with reduced setup time; order the TECWERK tool directly via Metav Werkzeuge or consult our specialists for application advice.

Zentrierbohrer DIN 333 Form B 3.15 mm – HSS centre drill with protective countersink by TECWERK

The Zentrierbohrer DIN 333 Form B 3.15 mm is a precision HSS centre drill designed to produce centre holes to DIN 332 Part 1, Form B, featuring a protective countersink and right‑hand cutting geometry for general metalworking use.

• HSS for high wear resistance
• Integrated protective countersink
• Right‑hand cutting geometry
• Senkwinkel 60/120° for versatile chamfers

Repeatable centring and stable drilling for production environments

The HSS body and DIN 333 Form B profile ensure accurate initial guidance and low runout during pilot drilling, which improves repeatability across batches. With a nominal diameter of 3.15 mm and a dedicated right‑hand cutting geometry, the tool produces clean centre points that reduce wobble when transferring to subsequent operations. The specified feed in steel — 0.03 mm/rev for materials up to 800 N tensile strength — gives a clear machining parameter for consistent hole quality, minimising rejects and downtime. These measurable characteristics support predictable cycle times and fit directly into established workshop processes.

Built‑in protective countersink to cut secondary work and improve fit

The addition of a protective countersink with interchangeable angles (noted as Senkwinkel 60/120°) creates the required chamfer in one pass, so the drilled centre is immediately compatible with countersunk fasteners or subsequent live‑centre seating. This design reduces the need for separate deburring or chamfering operations, saving handling time and lowering the risk of misalignment during assembly. For users requiring compliance with standards, the geometry matches the requirements for producing centre holes according to DIN 332 Part 1, Form B, making it straightforward to document process capability and inspection criteria.

Practical application notes and handling for workshop integration

The centre drill is suitable for general workshop and industrial applications where precise pilot centring is essential. The tool is right‑hand cutting and intended for common drilling setups such as drill chucks and turret tooling; its robust HSS composition delivers a balance of toughness and edge retention under standard machining conditions. When planning feeds and speeds, the stated feed of 0.03 mm/rev in steel up to 800 N provides a baseline; adapting speed to material and machine rigidity will extend tool life and maintain hole quality. The compact diameter and combined countersink function make this a space‑efficient choice for high‑mix, low‑volume operations as well as serial production.

FAQ

What materials is this centre drill suitable for?
This TECWERK centre drill is specified for use in steels up to 800 N tensile strength at the indicated feed of 0.03 mm/rev; further material testing is recommended for non‑ferrous or exotic alloys.

What does the protective countersink provide?
The integrated protective countersink creates a chamfer in the same operation, reducing secondary deburring and providing correct seating for countersunk parts when using the TECWERK centre drill.

Which standards does the tool comply with?
The geometry is designed for producing centre holes according to DIN 332 Part 1, Form B and follows the DIN 333 Form B profile for centre drills.

How should feeds and speeds be adapted?
Use the stated feed of 0.03 mm/rev in steel up to 800 N as a baseline; adjust spindle speed according to material hardness and machine rigidity to optimise tool life and hole quality.
