Drill bit Facom 222A.T8 NWKA FI 8.00 mm, length 35/117 mm

Drill bit Facom 222A.T8 NWKA FI 8.00 mm, length 35/117 mm is a solid, straight shank drilling tool designed for precision holes with an 8.00 mm nominal diameter. The bit features a 35 mm working length and a total length of 117 mm, manufactured to Facom quality standards for use in compatible handheld or bench drills. It is intended for general mechanical and metalworking applications where accurate, repeatable 8 mm holes are required.

Advantages

This Facom drill bit provides consistent 8.00 mm hole diameter tolerance and a robust construction that stands up to repeated use in workshop environments. The NWKA FI design supports precise chip evacuation and stable cutting action, while the overall length gives access to deeper drilling points compared to short bits. The straight shank allows secure clamping in standard chucks and compatibility with a wide range of drilling machines.

Suitable for

• Precision drilling in metal components
• General mechanical assembly and maintenance
• Handheld and bench drilling operations
• Projects requiring accurate 8 mm holes

Key specifications

• Nominal diameter: 8.00 mm
• Working (cutting) length: 35 mm
• Total length: 117 mm
• Design: solid, NWKA FI style
• Shank type: straight shank for standard chucks
• Intended material use: metalworking and general mechanical materials

How to use

Secure the drill bit in the tool chuck, ensuring proper centring and firm clamping. Select appropriate spindle speed and feed rate for the material being drilled and apply cutting fluid when drilling metals to reduce heat and improve chip removal. Begin drilling with light pressure to create a pilot entry, then proceed with steady feed until the required depth is reached. Retract the bit periodically for deep holes to clear chips and maintain cutting efficiency.

Usage recommendations

Use cutting fluid for ferrous metals, check chuck tightness before operation, and replace the bit when wear affects hole accuracy. Match drill speed and feed to the workpiece material to extend tool life and maintain hole quality.
