Centre drill DIN 333 Form A D.2,5mm HSS‑Co by TECWERK, right‑hand cutting, 60° countersink

The Centre drill DIN 333 Form A D.2,5mm HSS‑Co is a compact centre‑drilling tool designed to produce accurate pilot centres for subsequent drilling and turning operations in high‑strength and corrosion‑resistant materials

• HSS‑Co alloy for high wear resistance
• DIN 333 Form A geometry for accurate centring
• 60° countersink angle for standard centre holes
• Right‑hand cutting for conventional feeding

Precise centring that secures subsequent machining

The DIN‑compliant geometry ensures repeatable centre holes, reducing runout when transferring a workpiece between machines. The 60° countersink conforms to common centring standards, so the initial hole guides subsequent twist drills and live or dead centres with minimal misalignment. This results in fewer rejects, shorter set‑up times and improved process reliability when working on turned or drilled components.

Cobalt‑alloyed high‑speed steel for extended tool life

Constructed from HSS‑Co, the tool combines the toughness of high‑speed steel with cobalt‑enhanced hot‑hardness, which improves wear resistance under elevated temperatures. The right‑hand cutting geometry and specified feed 0.03 mm/rev in steel up to 800 N provide a balance between chip control and tool life. For workshops processing harder alloys or stainless CrNi steels, this composition delivers longer life than plain HSS while remaining economical compared with indexable solutions.

Built for demanding materials and easy process integration

Designed to create centre holes in materials with tensile strength above 800 N/mm² and in rost-, säure‑ und hitzebeständige CrNi‑stähle (corrosion‑ and heat‑resistant chromium‑nickel steels), the tool simplifies preparation for deep drilling and turning. Its compact design fits standard drill chucks and tailstocks, allowing straightforward replacement of worn items and fast reconditioning of the production cell. The combination of standardised form and robust material supports consistent cycle times and predictable maintenance intervals.
