Drill bit for metal Smart HSS cylindrical 3.5 mm, 10 pcs (11-035)

Drill bit for metal Smart HSS cylindrical 3.5 mm, 10 pcs are high-speed steel (HSS) straight-shank bits designed for creating precise 3.5 mm holes in mild steel and a range of other metals. Supplied as a pack of ten identical bits, they are suitable for use in handheld drills and drill presses where consistent hole diameter and durability are required for metalworking tasks, repairs and maintenance.

Advantages

These HSS cylindrical drill bits offer wear resistance and heat tolerance typical of high-speed steel, providing reliable cutting performance on metal surfaces. The straight shank design ensures secure clamping in standard chucks and compatibility with common drilling equipment. A uniform 3.5 mm diameter across the pack enables repeatable results when multiple holes of the same size are needed, reducing the need for frequent tool changes.

Suitable for

• Drilling holes in mild steel sheets, plates and components
• General metal repair and maintenance work
• Workshop and hobbyist metalworking projects
• Use with handheld power drills and drill presses

Key specifications

• Material: high-speed steel (HSS)
• Shank type: straight/cylindrical
• Cutting diameter: 3.5 mm
• Pack quantity: 10 pieces
• Suitable materials: mild steel and other metals

How to use

Select an appropriate drill speed and apply steady, moderate feed pressure when drilling metal to avoid overheating the bit. Secure the workpiece and clamp the bit firmly in the drill chuck. For improved results, mark the drilling point and use a centre punch to prevent the bit from wandering. Periodically withdraw the bit to clear chips and, if needed, use cutting fluid or coolant to extend tool life and maintain cutting performance.

Usage recommendations

For best performance, start with a slower spindle speed for tougher metals, keep the bit cool with cutting oil during prolonged drilling, and replace any bits showing signs of excessive wear or chipping to maintain hole quality and safety.
