Drill Bit Set Proedge HSS-G TiN for Metal, 11.0 mm, 5 pcs

Proedge HSS-G TiN drill bit set for metal, 11.0 mm diameter, 5 pieces. These bits are made from high-speed steel (HSS-G) with a titanium nitride (TiN) coating to increase surface hardness and reduce wear during repeated drilling in metal. The set is intended for drilling metal materials with standard drill chucks and is supplied as five identical 11.0 mm bits for consistent holemaking.

Advantages

The HSS-G material provides good toughness and heat resistance for metal drilling operations, while the TiN coating extends tool life by lowering friction and improving wear resistance. The uniform 11.0 mm diameter across the 5-piece set simplifies tool selection for repetitive tasks and reduces downtime spent changing sizes. These bits are compatible with standard drill chucks and are appropriate for workshop and professional environments where consistent metal drilling is required.

Suitable for

• Drilling through steel and ferrous metals
• Workshop and maintenance drilling tasks
• Repeated holemaking where multiple identical holes are needed
• Use with handheld and bench drill machines fitted with standard chucks

Key specifications

• Material: High-speed steel (HSS-G)
• Coating: Titanium nitride (TiN)
• Diameter: 11.0 mm
• Quantity: 5 pieces
• Application: Metal drilling

How to use

Select a suitable drill machine with a standard chuck capable of securely holding an 11.0 mm shank. Mark the drilling position on the workpiece and, if necessary, center-punch to prevent walking. Fix the workpiece firmly in a vice or clamp to avoid movement. Fit the Proedge HSS-G TiN 11.0 mm bit into the chuck and tighten securely. Use appropriate cutting speed and feed for the material being drilled, apply cutting lubricant when drilling harder metals, and clear chips frequently to maintain cutting efficiency. After use, clean the bits and store them dry to preserve the TiN coating and prevent corrosion.

Usage recommendations

For best results, use low to moderate cutting speeds on hard steels, apply a suitable cutting fluid to reduce heat and wear, and replace bits when wear affects hole size or surface finish. Always follow machine safety guidelines, wear eye protection, and secure the workpiece before drilling.
