Drill bit set MODECO HSS cylindrical for metal 12.5 mm, 5 pcs (MN-60-525)

Set of five MODECO HSS cylindrical shank drill bits with a 12.5 mm diameter, designed specifically for drilling metal. Manufactured from high-speed steel (HSS) to provide wear resistance and improved heat tolerance during continuous drilling operations. The cylindrical shank ensures secure clamping in standard drill chucks and bench drills, making the set suitable for workshop, maintenance and metal fabrication tasks that require precise through-holes in steel and non-ferrous metals.

Advantages

High-speed steel construction provides a balance of hardness and toughness for longer service life when cutting metal. The 12.5 mm diameter is appropriate for medium-to-large holes used in assembly and fabrication. Cylindrical shanks offer compatibility with a wide range of chucks and simple, reliable clamping. The uniform set of five bits allows quick replacement on the job and reduces downtime in repetitive drilling tasks.

Suitable for

• Drilling through mild and alloy steels
• Creating holes in non-ferrous metals such as aluminum and brass
• Workshop and maintenance repair tasks
• Metal fabrication and assembly work
• Use with hand drills and bench-mounted drill presses

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical
• Drill diameter: 12.5 mm
• Quantity: 5 pieces
• Intended material: steel and non-ferrous metals

How to use

Select a suitable drill chuck and secure the cylindrical shank firmly to prevent slippage. Mark the drilling point and use a center punch for accurate positioning on metal surfaces. Start at low speed to establish the hole, then increase speed moderately while applying steady pressure and using cutting oil or lubricant to reduce heat and improve chip evacuation. Withdraw the bit periodically to clear chips and avoid clogging; finish the hole with controlled speed to maintain dimensional accuracy.

Usage recommendations

Use cutting fluid when drilling steel to extend bit life and reduce heat. For thin or soft metals, reduce feed pressure to avoid burring. Inspect bits for wear or damage before use and replace when the cutting edge becomes dull to maintain clean holes and avoid excessive torque on the drill.
