Twist drill bit Verto 60H814 25 pc(s)

The Verto 60H814 twist drill bit set contains 25 HSS-G bits with diameters from 1.0 mm up to 13.0 mm, designed specifically for drilling metal. Made from high-alloy high-speed steel, this set provides a range of small to medium diameters suitable for precision metalworking and general workshop use. The set is presented as a coordinated assortment to cover common drilling needs in steel, cast iron, non-ferrous metals and metal alloys.

Advantages

High-alloy high-speed steel construction ensures good hardness and heat resistance for cutting metal. The range from 1.0 to 13.0 mm offers versatility for a variety of hole sizes without needing multiple individual purchases. Ground flutes and precise manufacturing provide accurate hole positioning and consistent chip evacuation during drilling. The set format keeps bits organized and ready for use in a workshop or on-site environment.

Suitable for

• Drilling holes in steel and stainless steel (with appropriate cutting speed and coolant)
• Working with cast iron and non-ferrous metals such as aluminium and brass
• General maintenance, repair and fabrication tasks in workshops
• Precision drilling for mechanical assemblies and metal fittings

Key specifications

• Material: high-alloy high-speed steel (HSS-G)
• Set size: 25 pieces
• Diameter range: 1.0 mm – 13.0 mm
• Application: designed for drilling metal
• Flute type: twisted flutes for chip removal

How to use

Select the appropriate diameter from the set for the required hole size, mark and center-punch the drilling location, and secure the workpiece. Use a drill press or hand drill at recommended cutting speeds for the metal type; apply cutting fluid or coolant when drilling stainless steel or harder alloys to reduce heat and extend drill life. Maintain steady feed pressure and allow the bit to clear chips periodically for consistent cutting performance.

Usage recommendations

Use progressive piloting for larger holes: start with a smaller diameter pilot hole from the set before enlarging to the final size. For high-temperature or heavy-duty drilling, use appropriate coolant, correct spindle speed and avoid excessive feed to prevent premature wear. Store bits in their case to protect cutting edges and preserve precision.
