FANAR HSS Cylindrical Metal Drill Bit 8.8 mm, model W2-101811-0880

The FANAR HSS Cylindrical Metal Drill Bit 8.8 mm (model W2-101811-0880) is a high-speed steel cutting tool designed for drilling precise through-holes in steel and non-ferrous metals. Its 8.8 mm cutting diameter and cylindrical shank make it compatible with standard drill chucks and bench-mounted drilling machines used in workshops and maintenance environments. The HSS material provides improved heat resistance and wear performance for general-purpose metalworking.

Advantages

This HSS drill bit offers consistent cutting performance when drilling steel and non-ferrous metals, with a geometry optimized for chip evacuation and hole accuracy. The cylindrical shank ensures secure clamping in common chucks and reduces runout, while HSS construction gives a balance of toughness and hardness for repeated use under moderate speeds and loads. Its 8.8 mm diameter is suited for preparing holes for fasteners or for clearance drilling in fabrication tasks.

Suitable for

• Drilling through mild and alloy steels
• Drilling non-ferrous metals such as aluminum and brass
• Workshop maintenance and general metal fabrication
• Preparing clearance holes for bolts and fasteners
• Use in hand-held drills and bench drills with standard chucks

Key specifications

• Material: High-speed steel (HSS)
• Cutting diameter: 8.8 mm
• Shank type: Cylindrical shank for standard chucks
• Typical application: Through-holes and clearance drilling in metals
• Suitable workpiece materials: Steel and non-ferrous metals

How to use

Select an appropriate drill speed for the workpiece material and secure the workpiece to prevent movement. Fit the 8.8 mm cylindrical shank into a properly tightened standard drill chuck. Use cutting fluid or coolant when drilling steel to reduce heat and extend tool life. Apply steady feed pressure, avoid excessive side load, and back the drill occasionally to clear chips when drilling deeper holes.

Usage recommendations

For best results, start with a pilot hole if precision or alignment is critical, maintain recommended spindle speeds for HSS in the chosen material, and use cutting fluid when machining steels. Inspect the drill for wear or chipping before reuse and replace when cutting performance degrades.
