TECWERK centre drill DIN 333 Form A, Ø 3.15 mm, HSS

TECWERK centre drill DIN 333 Form A, Ø 3.15 mm, HSS — a compact centring tool designed for accurate preparation of centre holes to DIN 332 where no protective countersink is required

• HSS centre drill, DIN 333 Form A
• 60° countersink angle for DIN 332 centres
• Precise feed 0.03 mm/rev in steel up to 800 N
• Robust design for general-purpose centring

Accurate starts for reliable drilling cycles

A centre drill to DIN 333 Form A delivers a defined intersection for subsequent machining and prevents runaway of the following twist drill. The 60° countersink angle matches the geometrical requirement for standard centre holes to DIN 332, ensuring dependable contact with live or fixed centres and minimising eccentricity at first contact. The specified feed of 0.03 mm/rev in steel environments up to 800 N supports a controlled cut that reduces burr formation and promotes concentricity, which in turn shortens cycle times and lowers scrap rates.

Hard-wearing HSS construction for workshop use

Constructed from HSS, this centring tool offers a balance of toughness and wear resistance suited to everyday industrial use. The high-speed steel tip retains sharpness through repeated use and is compatible with customary regrinding practices, extending tool life and reducing replacement frequency. As a general-purpose centring solution, the tool provides consistent performance across a variety of ferrous applications where a defined centre is required before holemaking.

Standards conformity that simplifies process planning

Conformity with established standards removes guesswork from process specification: DIN 333 Form A defines geometry and intended use, while alignment to DIN 332 clarifies the target centre profile. This alignment supports predictable results when integrating the centring operation into CNC programmes or manual setups, helping to reduce setup iterations and improve first-pass yield. The combination of standard geometry and repeatable feed parameters aids tool selection and inventory rationalisation.

Practical guidance for selection and use

Selecting a centre drill with the correct geometry ensures compatibility with downstream tooling. The absence of a protective countersink in this design means the centring cut is pure and precise, so the tool is best used where a clean centre is required for turning between centres or for accurate pilot drilling. Maintain recommended feeds and monitor wear: a visible dulling of the cutting lip is the primary indicator for regrinding or replacement to preserve hole quality and machine efficiency.

FAQ

What materials is this centre drill suitable for?
The TECWERK centre drill (centre drill, SKU 2000861573NW) is specified as a general-purpose HSS tool; it is primarily intended for use in common ferrous materials where a defined centre is required prior to drilling or turning.

How does the 60° countersink angle affect compatibility with centres?
A 60° countersink angle aligns with the geometry for centre holes defined in DIN 332, so the centring feature produced by this tool meets common centre-point contact requirements for live and fixed centres when using the TECWERK centre drill.

Is the feed rate critical for hole quality?
Yes, the recommended feed of 0.03 mm/rev in steel up to 800 N is given to balance cutting action and finish; adhering to this parameter with the TECWERK centring tool helps to avoid burrs and ensures concentric starts for subsequent drilling.

Can the tool be re-ground or re-sharpened?
Being manufactured from HSS, the centring tool can be re-ground following standard workshop practice to restore cutting geometry, which extends service life and supports cost-effective tool management.

What does "without protective countersink" imply for applications?
The description indicates the centre drill creates a direct, standard-profile centre hole rather than a protective or expanded countersink; this is ideal where a precise pilot centre is required for accurate turning or drilling operations.
