Drill bit Smart HSS for metal 10.5 mm — set of 5 (brand: Smart)

Smart HSS drill bit for metal, 10.5 mm diameter, supplied as a set of five identical bits. Manufactured from high-speed steel, these drill bits are designed for cutting clean holes in steel, non-ferrous metals and many common alloys. The 10.5 mm size is suitable for creating medium-diameter holes for fasteners, fittings and passages in workshop repair, fabrication and maintenance work. Bits in the set are compatible with standard hand drills and drill presses and are balanced for stable rotation during drilling.

Advantages

The HSS material provides a combination of hardness and toughness that supports effective cutting at moderate speeds and resists wear during repeated use. Supplied as a set of five, the pack reduces downtime by providing spare bits for continuous work. The geometry of the tip and flute ensures efficient chip evacuation and a reliable drilling start, improving hole accuracy and surface finish in metal substrates. These bits are versatile for both portable and bench-mounted drilling equipment.

Suitable for

• Drilling holes in steel and iron components
• Working with non-ferrous metals such as aluminium and copper
• Workshop repairs, maintenance and assembly tasks
• Drill press or hand drill operations

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 10.5 mm
• Package quantity: 5 identical drill bits
• Intended materials: steel, non-ferrous metals and common alloys
• Compatible equipment: hand drills and drill presses

How to use

Select a drill chuck that securely holds a 10.5 mm shank and clamp the workpiece to prevent movement. Mark the drilling position and, if necessary, center-punch the mark to improve tip location. Use appropriate cutting speed and steady feed pressure for the specific metal: lower RPM for harder steels, higher RPM for softer non-ferrous metals. Apply cutting fluid or lubricant when drilling steel to reduce heat and improve tool life. Withdraw the bit periodically to clear chips and avoid clogging the flutes.

Usage recommendations

Store the bits in a dry place to prevent corrosion and inspect cutting edges before use. Replace a worn or chipped bit to maintain hole quality. When drilling thicker or hardened steels, consider pre-drilling with a smaller pilot bit and use appropriate coolant to extend tool life.
