TECWERK centre drill DIN 333 Form A, 0.8 mm HSS (right-hand cutting)

A TECWERK centre drill DIN 333 Form A, 0.8 mm HSS for reliable centre-hole creation to DIN 332 standards, offering a 60° countersink angle and compact overall length for fine machining tasks

• HSS construction for lasting edge retention
• DIN 333 Form A geometry for accurate centring
• 60° countersink angle for standard centre holes
• Single-ended, right-hand cutting, 25 mm length

Accurate centring for repeatable machining

The TECWERK centre drill combines HSS material and the DIN 333 Form A profile to produce consistently true centre holes that aid secure seating for lathe centres and precise locating for subsequent operations. The 60° countersink conforms to common standards, which reduces setup variation and helps maintain process repeatability. The robust geometry is designed for general-purpose use while providing defined axial guidance during initial drilling stages, improving hole concentricity and reducing rework.

Predictable cutting data and performance

Engineered for steady feeds, the tool specification includes a recommended feed in steel (up to 800 N): 0.01 mm/rev, ensuring a stable cutting regime for small-diameter centre drilling. The right-hand cutting direction and single-ended execution support straightforward tool clamping and predictable chip formation. Clear cutting data simplifies process planning and enables integration into existing production sequences with reduced trial runs, contributing to improved cycle-time reliability.

Compact form and handling advantages

With a nominal diameter of 0.8 mm and an overall length of 25 mm, the centre drill is well suited to confined workpieces and precision setups. The compact dimensions shorten cantilever length and help reduce deflection during engagement. The single-ended design eases storage and replacement logistics, while the HSS composition balances toughness and edge retention for frequent short-cycle centre drilling tasks without the need for exotic tooling.

Practical applications and process benefits

Designed for the general-purpose creation of centre holes to DIN 332, this centre drill supports turning preparations, pilot-hole starts and accurate locating marks across routine metalworking tasks. The standardised geometry reduces the need for additional chamfering operations and helps streamline tool inventories when combined with consistent mounting practices. Integrating a standardised centre drill like this into production improves operational clarity and contributes to fewer machine stops for tool-related issues.
