Centre drill DIN 333 Form R Ø3.15 mm, HSS – TECWERK

A Centre drill DIN 333 Form R Ø3.15 mm HSS engineered to produce accurate centre holes for metalworking, lathe preparation and general workshop use.

• HSS construction for durability
• DIN 333 Form R with radius tip
• 60° countersink angle for standard centres
• 8 mm shank, 50 mm overall length

Consistent centre holes for reliable machining starts

The combination of HSS material and the Form R geometry ensures a balance of toughness and edge retention, reducing breakouts when preparing lathe centres. The 60° countersink angle matches conventional centre standards, so the centring operation produces stable seating for workpieces. For steel applications up to 800 N a feed of about 0.03 mm/rev is recommended, which helps maintain concentricity while avoiding excessive axial loads on the tool.

Versatile use across workshop tasks

Designed for general-purpose workshop applications, this centring tool performs well when preparing holes for turning, facing and repositioning operations. The radius tip of Form R gives a controlled cutting entry that eases alignment and reduces the risk of wandering on curved or uneven surfaces. Where a precise start is required before drilling or reaming, the centring tool provides a reliable pilot that improves subsequent tool life and component quality.

Practical handling and toolholder compatibility

With an 8 mm shank and 50 mm overall length, the tool fits standard 8 mm collets and chucks used in drills and lathe tailstocks. The right-hand cutting orientation is compatible with typical spindle rotation, permitting straightforward programme integration and manual use. The absence of a protective countersink (no pilot countersink fitted) keeps the geometry simple, making it straightforward to seat the tool in conventional holders and to inspect the cutting tip.

Supply reliability and workshop support

Delivered in a compact pack, the centring drills are supplied in a pack size of 5, suitable for replenishment in busy workshops. Metav’s procurement and logistics centre in Emmerich acts as a quality filter for the European market, combining extensive product range with consistent availability and clear order handling.

FAQ

What advantage does Form R offer over a standard centre point? Form R provides a radius tip that gives a gentler entry and improved stability when creating centre bores; the TECWERK centre drill with Form R reduces wandering and supports reliable turning starts.

Which feed and cutting direction are recommended for this tool? A feed of approximately 0.03 mm/rev in steel up to 800 N is recommended, and the tool is designed with a right-hand cutting orientation for standard spindle rotation.

What holder size is required for this centre drill? The tool has an 8 mm shank, which fits common 8 mm collets and drill chucks used in workshop drills and tailstocks.

Is this centre drill suitable for preparing lathe centres and pilot holes? Yes, the geometry and 60° countersink angle make the tool suitable for preparing lathe centres and pilot holes according to conventional centre standards.

How is the product supplied and how can it be identified? The TECWERK centre drill is supplied in packs of five and can be identified by the article number 2000861953NW.
