NC spot drill 20 mm, solid carbide, TiAlN, 90° — TECWERK

The NC spot drill 20 mm is a purpose-built centre/spot drill for position-accurate starts and simultaneous chamfering on NC machines and drilling rigs

• Solid carbide with DIN 6535-HA shank
• TiAlN coating for increased tool life
• 90° geometry for accurate centring and chamfering

Faster, more reliable starts for NC production

The combination of a solid carbide body and a TiAlN surface finish produces a tool that resists wear and sustains sharp cutting edges under repetitive positioning operations. Designed for short-cycle, high-precision use, this centre drill reduces the need for secondary chamfering by performing centring and edge preparation in a single pass. The cylindrical shank DIN 6535-HA ensures secure clamping and repeatable concentricity, which supports consistent hole quality and fewer reworks on assembly-critical components.

Suited to demanding materials and stable feeds

This tool is specified for use on high-strength steels, cast steel, grey cast iron, stainless steel and non-ferrous metals, making it versatile across typical metalworking shops. With a recommended feed in steel up to 800 N of 0.16 mm/rev, the geometry and coating balance durability and cutting performance to maintain form and surface finish during aggressive positioning cycles. Right-hand cutting flutes ensure conventional spindle directions on CNC lathes and machining centres remain fully compatible.

Practical benefits for process efficiency and tool handling

By combining centring and chamfering operations, cycle times are shortened and handling steps are reduced, which streamlines workflows on both NC machining centres and conventional drill rigs. The 90° tip produces clear chamfer definition that eases thread starts and improves fastener seating. The tool’s specification minimises burr formation and supports downstream processes such as tapping or automated assembly, while the robust coating and right-hand cutting design lower the frequency of tool changes and interventions at the machine.

FAQ

What materials can be machined with this spot drill?
The TECWERK NC spot drill is suitable for high-strength steels, cast steel, grey cast iron, stainless steel and non-ferrous metals, making it a versatile choice for mixed production environments.

Which shank and clamping standard does the tool use?
The tool has a cylindrical shank to DIN 6535-HA, providing standardised clamping compatibility with many chucks and holders.

What feed rate is recommended for steel?
Recommended feed in steel up to 800 N is 0.16 mm/rev, which balances cutting performance and tool life for the specified materials.

Is the TiAlN coating advantageous for stainless steel?
Yes, the TiAlN coating increases thermal resistance and surface hardness, improving wear resistance and extending cutting life when working with stainless steels and other demanding materials.

Which machines are appropriate for this tool?
Designed for position-accurate starts, the spot drill performs best on NC machines and drilling machines where repeatable clamping and precise spindle control are available.
