Drill bit Facom 222A.T11.5 NWKA Ø11.50 mm length 94/142 mm

Facom 222A.T11.5 NWKA Ø11.50 mm length 94/142 mm is a precision twist drill designed for drilling metal and other hard materials where a long-reach cutting edge is required. The bit has a nominal diameter of 11.50 mm with a cutting length of 94 mm and an overall length of 142 mm, making it suitable for tasks that need access into recessed areas or through thicker workpieces. It is intended for professional and industrial use in maintenance, machining and fabrication environments.

Advantages

This drill bit offers accurate hole sizing and stable cutting performance due to precise manufacturing tolerances. The extended overall length provides reach for drilling into deep or hard-to-access locations while maintaining rigidity appropriate for its diameter. It is compatible with standard toolholders and drill chucks, enabling straightforward integration into workshop and portable drilling setups. The component is designed to withstand machining stresses typical in metalworking applications.

Suitable for

• Through-holes and deep holes in steel and non-ferrous metals
• Maintenance and repair work in confined or recessed spaces
• Machining and fabrication operations requiring extended-reach drilling

Key specifications

• Nominal diameter: 11.50 mm
• Cutting length: 94 mm
• Overall length: 142 mm
• Bit type: long-reach twist drill
• Intended materials: metals and other hard materials

How to use

Select an appropriate drill speed and feed for the material being machined and secure the workpiece to prevent movement. Install the drill bit in a suitable chuck or toolholder, ensuring correct centring and firm clamping. Use coolant or cutting fluid as required for metalworking to reduce heat and extend tool life. Begin drilling with controlled, steady pressure and retract periodically to clear chips when drilling deep holes. Inspect the hole dimension and surface finish after completion and deburr as necessary.

Usage recommendations

For best results when drilling metals, use appropriate cutting fluid, moderate speeds, and steady feed rates. Ensure the drill is clamped correctly and that the workpiece is supported to minimise runout and vibration. Replace the bit when wear or damage affects hole quality.
