Drill bit set Proedge HSS-G TiN 11.5 mm (5 pcs) – metal drilling

Proedge HSS-G TiN drill bit set for metal, 11.5 mm diameter, contains five identical bits designed for routine metal drilling tasks. Each bit is made from high-speed steel (HSS-G) and finished with a titanium nitride (TiN) coating to extend tool life and maintain cutting performance under higher temperatures. The set is intended for use with hand drills and drill presses and is suitable for drilling into common ferrous materials such as steel and cast iron in fabrication, maintenance and repair settings.

Advantages

The HSS-G core provides toughness and resistance to abrasion while the TiN coating reduces friction and improves heat resistance, allowing for longer cutting times and more consistent hole quality. The 11.5 mm diameter offers a mid-range size for through holes and clearance holes in metalwork. The uniform set of five bits simplifies tool management for repetitive tasks and reduces downtime for bit changes.

Suitable for

• Drilling holes in steel plates and structural steel components
• Maintenance and repair work on metal machinery and equipment
• Workshop fabrication tasks using hand drills and drill presses
• Creating clearance or through holes for bolts and fasteners in iron and steel

Key specifications

• Material: high-speed steel (HSS-G)
• Coating: titanium nitride (TiN)
• Diameter: 11.5 mm
• Quantity: 5 pieces
• Recommended use: metal drilling (ferrous materials such as steel and iron)
• Suitable tools: hand drills and drill presses

How to use

Secure the workpiece firmly in a vise or with clamps to prevent movement. Select a compatible drill chuck that accepts an 11.5 mm shank and install the Proedge HSS-G TiN bit with proper tightening. Use appropriate cutting speed and feed for steel, apply cutting fluid or lubricant to reduce heat and improve chip evacuation, and start drilling with steady pressure. Break through the material carefully and retract the bit periodically to clear chips for cleaner holes and prolonged bit life.

Usage recommendations

For best results when drilling steel, use moderate cutting speeds, apply suitable cooling or lubrication, and replace bits when wear or loss of cutting edge quality is observed. Store the bits in a dry place to avoid corrosion and keep them in their case or organizer to prevent damage.
