Drill Bit for Metal MODECO HSS cylindrical 12 mm, set of 5 (MN-60-520)

The MODECO HSS cylindrical drill bit set contains five 12 mm high-speed steel bits designed for drilling metal and similar materials. Each bit features a cylindrical shank and an HSS cutting body intended for general metalworking, workshop repairs and machinery maintenance. The set is compatible with standard hand drills and drill presses that accept cylindrical shanks of this diameter and provides a consistent 12 mm hole size for repeatable operations.

Advantages

High-speed steel construction offers good wear resistance and heat tolerance for common metal drilling tasks. Cylindrical shanks ensure straightforward mounting in standard drill chucks and allow use in both hand-held drills and bench drills. The set format of five identical bits provides backup tools for continuous work and reduces downtime from dulling or breakage. The 12 mm diameter is a common size for through-holes, fastener clearances and preparatory work in metal fabrication.

Suitable for

• Drilling mild steel, stainless steel thin sheets and metal plates
• Workshop maintenance and machinery servicing
• Creating clearance holes for bolts and fasteners
• Use in hand drills and drill presses with cylindrical chucks

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical
• Drill diameter: 12 mm
• Quantity in set: 5 pieces
• Intended applications: Metal drilling and similar materials

How to use

Select an appropriate cutting speed and feed for the metal being drilled, secure the workpiece, and mount the 12 mm HSS cylindrical bit firmly in the chuck. Use cutting fluid or coolant when drilling harder or thicker metals to reduce heat build-up and extend tool life. Apply steady, moderate pressure and withdraw the bit periodically to clear chips when drilling deep holes. Replace bits from the set as they wear to maintain hole quality and avoid excessive force on the drill.

Usage recommendations

For best results, match spindle speed to material hardness, use appropriate cutting lubricant, and clamp the workpiece to prevent movement. Do not use the bits on masonry, concrete or materials with embedded abrasives. Store the set in a dry place to avoid corrosion and inspect bits for wear before use.
