Drill Bit for Metal Smart HSS 3.5 mm Solid Shank – 10 pcs (24-035)

Solid shank high-speed steel (HSS) drill bits by Smart, diameter 3.5 mm, pack of 10. These cylindrical HSS bits are designed for drilling steel and non-ferrous metals, offering a balance of wear resistance and heat tolerance suitable for general metalworking. The 3.5 mm diameter and solid shank construction make them compatible with handheld drills and drill presses used in maintenance, fabrication and repair tasks.

Advantages

Smart HSS drill bits feature a solid shank for secure chuck gripping and consistent concentricity. The high-speed steel composition provides good hardness and wear resistance for routine metal drilling, while the geometry of the cutting edges ensures reliable chip evacuation and stable drilling performance. Supplied in a pack of 10, they are convenient for repetitive tasks and on-site work where quick replacement is needed.

Suitable for

• Drilling holes in mild steel, stainless steel and non-ferrous metals
• Maintenance and repair of machinery and equipment
• Metal fabrication, prototyping and small-scale production
• Use with handheld electric drills and bench drill presses

Key specifications

• Material: high-speed steel (HSS)
• Shank type: solid cylindrical shank
• Diameter: 3.5 mm
• Quantity: 10 pieces per pack
• Application: drilling in ferrous and non-ferrous metals
• Compatibility: suitable for standard drill chucks (handheld and bench)

How to use

Secure the drill bit in the chuck of a handheld drill or drill press so the shank is fully gripped and concentric. Mark and, if necessary, center-punch the drilling location on the workpiece to reduce walking. Use appropriate cutting speed and feed for the material being drilled; lower speeds are recommended for harder steels. Apply cutting fluid or lubricant when drilling steel to reduce heat and extend bit life. Withdraw the bit periodically to clear chips and avoid clogging.

Usage recommendations

For best results, use a suitable cutting lubricant when drilling ferrous metals, avoid excessive feed that can cause bit breakage at this small diameter, and replace worn bits to maintain hole accuracy and surface finish.
