1.25mm Centre Drill DIN 333 Form A 60° HSS Right-Hand, Pack of 5 - TECWERK

Take advantage of the HSS construction and the DIN 333 Form A geometry with a 60° countersink for reliable centre preparation and repeatable positioning; order via Metav Werkzeuge or consult the Metav advisors for application-specific guidance.

Centre drill DIN 333 Form A, 1.25 mm HSS – TECWERK

The Centre drill DIN 333 Form A 1.25 mm is a short pilot and countersink combination designed for accurate 60° centre holes in metalworking preparation.

• HSS ground for high dimensional stability
• DIN 333 Form A geometry with 60° angle
• Suitable for general-purpose centre drilling

Consistent positioning for downstream machining

The combination of solid HSS construction and the standardised DIN 333 geometry delivers a dependable method for producing clean centre holes prior to turning or drilling. The integrated pilot and countersink ensure concentric pre‑centres with a defined 60° seating, reducing runout when transferring work between centres or when starting conventional drills. Because the tool is specified as Form A, the pilot and chamfer are matched to the standard, which simplifies inspection and tool replacement in serial production. The right‑hand cutting design and the specified feed behaviour contribute to predictable chip formation and less set‑up time.

Proven geometry for reliable cutting performance

The 60° tip angle and the compact Form A profile are optimised for stable initial engagement and minimal wandering on curved or uneven surfaces. With a nominal diameter of 1.25 mm, the tool is suitable for fine centre preparation on small shafts and workpieces where accuracy matters. The data sheet specifies a recommended feed in steel up to 800 N of 0.02 mm/rev, which translates into smooth cutting and a reduced risk of burrs at the hole edge. The combination of these measurable parameters supports throughput optimisation and quality assurance in batch processing.

Practical use and material considerations

This short centre drill is intended for general use in metalworking and offers a straightforward solution where a defined centre is required before subsequent machining operations. The right-hand cutting direction matches standard spindle rotation; the HSS substrate provides toughness for interrupted cuts and everyday workshop use. For applications requiring different materials or harder alloys, check the tool list for specific grades or coatings; for standard steel and cast components the HSS, DIN 333 specification and the compact geometry provide a robust, low‑maintenance option that helps to reduce rejects and rework.

FAQ

How does DIN 333 Form A differ from other centre drill forms?
Form A combines a pilot and a 60° countersink in a compact geometry; the TECWERK centre drill to DIN 333 provides a standardised seating angle and pilot length for consistent centre hole preparation.

Is the 1.25 mm size suitable for small shaft centres?
Yes, the 1.25 mm nominal diameter is intended for fine centre preparation on small shafts and workpieces where precise seating and low runout are required.

What cutting parameters are recommended for steel?
For steel up to the specified condition, a feed of 0.02 mm/rev is given; this setting promotes stable chip removal and reduces burr formation when using the HSS centre drill.

Can this centre drill be used on hardened materials?
The tool is manufactured from HSS and is intended for general workshop materials; for pre‑hardened or high‑alloy materials, alternative grades or coated variants should be considered.
