Drill bit for metal Tvardy HSS 11.00 mm

Drill bit for metal Tvardy HSS 11.00 mm is a straight-shank high-speed steel cutting tool designed for accurate hole-making in metal. The 11.00 mm cutting diameter and HSS material provide a balance of hardness and toughness for general metalworking, suitable for use with standard keyed or keyless drill chucks in workshops, maintenance bays, and production lines.

Advantages

The HSS construction offers good heat resistance and wear properties compared with standard carbon-steel bits, allowing sustained drilling at moderate speeds in both ferrous and non-ferrous metals. The straight shank ensures stable clamping in common drill chucks and simplifies bit changes. The 11.00 mm diameter is a common size for fabrication and repair work, enabling precise, clean holes with minimal burr when used with appropriate feeds and speeds.

Suitable for

• Drilling holes in mild steel, stainless steel, aluminum, and other non-ferrous metals
• Workshop fabrications and metal repair tasks
• Maintenance and installation work requiring standard-sized holes
• Production runs with manual or bench-mounted drilling machines

Key specifications

• Cutter material: high-speed steel (HSS)
• Shank type: straight shank for standard drill chucks
• Cutting diameter: 11.00 mm
• Recommended use: general metal drilling (ferrous and non-ferrous)
• Typical mounting: keyed or keyless drill chuck

How to use

Secure the drill bit in the drill chuck ensuring the shank is fully seated and tightened. Select an appropriate spindle speed and feed rate for the material being drilled—lower speeds for stainless steel, higher speeds for aluminum—apply steady, moderate pressure, and use cutting fluid when drilling harder metals to reduce heat and extend tool life. Clear chips from the hole periodically and back the bit out occasionally when drilling deep holes to prevent clogging and overheating.

Usage recommendations

For best results, pair the 11.00 mm HSS bit with cutting fluid and a drill press or stable handheld drill. Adjust speed and feed according to the workpiece material: use slower speeds and light pecking for stainless steel, and higher speeds with continuous feed for aluminum and softer alloys. Inspect the bit for wear or dulling and replace when cutting performance declines to maintain hole quality.
