Drill bits Proline HSS for metal 4.5 mm, set of 2

Proline HSS metal drill bits, diameter 4.5 mm, set of 2. Made from high-quality HSS steel with a 135° split point and adjustable flute geometry for stable drilling in metal. Working length 47 mm, overall length 87 mm.

Advantages

The HSS construction provides durability and heat resistance when drilling metal. The 135° split-point tip reduces walking and improves centering, while the adjustable flute angle helps evacuate chips for cleaner holes. The compact dimensions make these 4.5 mm bits suitable for precision metalwork.

Suitable for

• Drilling holes in steel and other ferrous metals
• Precision metalworking and fabrication
• Workshop and maintenance tasks requiring 4.5 mm holes

How to use

Secure the drill bit firmly in the chuck of a drill or drill press. Mark the drilling position and, if necessary, use a center punch to prevent slipping. Begin drilling at low speed to establish the hole, then increase speed as appropriate for the metal type. Apply steady pressure and use cutting fluid or coolant for harder metals to extend bit life. Remove chips periodically to avoid clogging.

Usage recommendations

Use appropriate personal protective equipment and select drill speed according to the metal being worked. For stainless steel or hardened materials, use cutting fluid and moderate speed; for softer metals, higher speeds are acceptable. Replace bits when wear or chipping reduces drilling quality.
