Drill bit Dedra pilot for metal 100 mm HSS

Dedra pilot drill bit for metal, 100 mm length, made of high-speed steel (HSS) is designed for making precise pilot holes in metal workpieces. The 100 mm overall length supports deeper drilling tasks and positioning before using larger diameter cutters or taps. The HSS material provides improved wear resistance and heat tolerance compared with standard carbon steel, allowing consistent performance during metal fabrication, repair and assembly operations when used with hand drills or drill presses.

Advantages

This HSS pilot drill bit combines hardness and toughness for reliable hole-starting performance in metals. Its 100 mm length enables drilling through thicker sections or creating stable pilot holes that guide subsequent larger drills or threading tools. The high-speed steel composition helps resist softening at elevated cutting temperatures, reducing workpiece discoloration and bit wear during extended or repetitive drilling sequences.

Suitable for

• Creating pilot holes in mild steel, stainless steel and non-ferrous metals
• Use with hand drills for on-site repairs and maintenance
• Use with drill presses for workshop fabrication and assembly
• Preparing holes before tapping or reaming

Key specifications

• Overall length: 100 mm
• Material: High-speed steel (HSS)
• Intended use: Pilot drilling in metal
• Compatibility: Suitable for hand-held drills and drill presses
• Performance: Wear-resistant and heat-tolerant cutting edge properties

How to use

Select an appropriate drill speed and clamping method for the metal being worked; secure the workpiece to prevent movement. Fit the pilot drill bit into the drill chuck and ensure it is aligned. For hand-held drilling, start at low speed to establish the hole, then increase speed as appropriate for the material. For drill press use, align the bit with the marked position and apply steady feed. Use cutting fluid when drilling harder metals to extend bit life and improve chip evacuation. Withdraw the bit periodically on deeper holes to clear chips and reduce heat buildup.

Usage recommendations

For best results, match drilling speed and lubrication to the type of metal: lower speeds and cutting fluid for stainless steels and harder alloys, moderate speeds for mild steel and higher speeds for softer non-ferrous metals. Store the HSS pilot bit in a dry place and inspect cutting edges before use; regrind as needed following manufacturer guidelines to restore geometry.
