Metal drill bits Dedra HSS Stal 4341 135° tip 6×93 mm set of 10

Set of 10 Dedra metal drill bits made from HSS Stal 4341 steel, each with a 6×93 mm size and a 135° point angle. These twist drills are engineered for drilling into metals and similarly hard materials, offering precise penetration, efficient chip evacuation and reliable concentricity. The 135° tip reduces walking on hard surfaces and improves hole quality for through and blind drilling operations. The set is suitable for use in handheld drills and drill presses for metalworking, maintenance and fabrication tasks.

Advantages

HSS Stal 4341 construction provides a balance of hardness and toughness, maintaining cutting edge retention during repeated metal drilling. The 135° tip geometry improves centering on hard surfaces and reduces the need for pilot holes, while the standard 6 mm diameter and 93 mm length provide versatility for common workshop and industrial tasks. The twist-flute design supports effective chip removal to help maintain drilling speed and reduce heat buildup.

Suitable for

• Drilling holes in steel, iron and other ferrous materials
• Through-hole and blind-hole drilling in metal components
• Use with handheld electric drills and bench drill presses
• Maintenance, repair and fabrication workshop tasks

How to use

Secure the workpiece with an appropriate clamp or vise to prevent movement. Choose a suitable cutting speed for the material being drilled and, if available, use lubricating or cooling fluid to reduce heat and wear. Insert the 6 mm drill bit into the drill chuck, ensure it is properly centered and tightened, then start drilling at low speed to establish the hole and increase speed as required. Apply steady axial pressure and withdraw periodically for chip clearing on deep holes. After use, clean chips from the flutes and store the bits in a dry case.

Usage recommendations

For optimal life and performance, use cutting fluid when drilling stainless steels or hard alloys, select appropriate drill speed based on material hardness, and avoid excessive axial force to reduce risk of chipping. Inspect bits for wear or damage before each use and replace when cutting edges are dull.
