Precise centre bores are achieved with a HSS construction, DIN 333 Form R radius tip and a 60° countersink angle, delivering repeatable results for turning preparation and general workshop drilling. Order the centre drill directly via Metav Werkzeuge or ask our consultants if needed. 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.

Centre drill DIN 333 Form A, 3.15 mm – HSS, TiN, right-hand (TECWERK) The centre drill DIN 333 Form A, 3.15 mm, a short, rigid centre drill designed for precise centre-hole formation in general machining and workshop applications. HSS substrate with TiN coating DIN 333 Form A geometry 60° centring angle for accurate starts Consistent starts that reduce run-out and rework A reliable first operation improves the whole machining sequence. The short, rigid geometry of this centre drill ensures a precise 60° centre point that reduces lateral run-out when drilling or turning. The Form A profile to DIN 333 gives a stable cutting engagement, which is especially beneficial when facing tight tolerances on shafts or when preparing centres for subsequent drilling or turning. The predictable behaviour of the tool supports repeatable setup and quicker cycle time, translating to fewer rejected parts and smoother production flows. Wear resistance and longer service life under load The combination of HSS substrate and TiN coating provides balanced toughness and surface hardness: the substrate resists chipping, while the coating reduces friction and wear on the cutting edges. For series workrooms where tool changes interrupt throughput, this centre drill maintains edge life and surface finish for longer periods. The TiN layer also aids chip release and reduces built-up edge, which keeps the centring operation clean and consistent across batches. Clear cutting data for efficient process planning Process planners benefit from explicit empirical data: the tool is specified for a feed in steel (up to 800 N) of 0.03 mm/rev, enabling straightforward integration into existing programmes and feeds. The 3.15 mm nominal diameter and the compact overall length contribute to rigidity, while the right-hand cutting direction matches standard spindle rotations. These measurable parameters allow engineers to estimate tool life, plan reorders and set reliable process windows without prolonged trial runs. Easy fitment and compatibility with common holders With an 8 mm shank and 50 mm overall length, the centre drill fits typical toolholders and tailstock collets found in general workshops and small production cells. The short design minimises deflection and is therefore suitable for creating centre holes in shafts and blanks prior to drilling or turning operations. Its conformity with the DIN standard simplifies stockkeeping and ensures the dimensioning aligns with tooling charts and fixture setups.

This robustness translates into fewer interruptions on the shop floor and a more predictable production rhythm. Integrated protective countersink for safer setup The version with protective countersink combines centring and a guarded countersink in one tool, reducing tool changes and alignment errors. The dual‑angle countersink (60/120°) offers reliable seating for centre holes and helps protect the workpiece surface during initial engagement. Right‑hand cutting action complements standard spindle rotation and ensures conventional chip evacuation. In practice, the integrated countersink lowers setup complexity and minimises the risk of damaging delicate workpiece faces during pilot drilling. Measurable feed and handling data for efficient programming For programmable and manual machine operation, the tool’s recommended feed in steel (up to 800 N) is 0.05 mm/rev, a conservative value that balances surface quality and tool life. The 80 mm overall length offers accessibility for through‑work and shallow recesses while keeping overhang low to preserve rigidity. These measurable parameters assist process planners in standardising cycle times and calculating throughput for repetitive tasks. Clear numeric data supports rapid CAM setup and consistent results across batches.
