Drill bit DeWalt HSS straight shank for metal 5.5 mm DT5147

DeWalt HSS drill bit with a straight shank, 5.5 mm diameter, designed for precision drilling in metal. The bit is made from high-speed steel (HSS) to provide improved heat resistance and wear performance when machining steel and other metals. Its cylindrical shank fits standard chucks on hand drills and drill presses, offering a stable connection for drilling tasks in metalworking, maintenance and installation work.

Advantages

The high-speed steel construction sustains cutting performance at elevated temperatures and reduces wear compared with standard carbon steel bits. The 5.5 mm diameter provides a common hole size for many metalworking applications and is compatible with fractional and metric tool sets. The straight (cylindrical) shank ensures reliable clamping in keyed and keyless chucks, and the precision-ground flutes promote efficient chip removal and consistent hole quality.

Suitable for

• Drilling holes in mild steel, stainless steel and non-ferrous metals
• Workshop use with handheld drills and drill presses
• Maintenance, repair and installation tasks requiring small to medium holes in metal parts

Key specifications

• Material: high-speed steel (HSS)
• Shank type: straight (cylindrical) shank
• Drill diameter: 5.5 mm
• Intended application: drilling metal
• Compatible with: standard keyed and keyless chucks on drills and drill presses

How to use

Select a compatible drill or drill press and secure the bit in the chuck, making sure the straight shank is fully seated and clamped. Mark and center-punch the drilling location on the metal surface to prevent wandering. Start at a low speed to establish the hole, then increase speed as appropriate for the material thickness and drill size. Apply steady, moderate feed pressure and allow the HSS bit to cut without forcing. Use cutting fluid or lubricant for tougher steels to reduce heat and extend bit life. Retract the bit periodically to clear chips if drilling deep holes.

Usage recommendations

Use appropriate personal protective equipment, clamp workpieces securely, and choose feed rate and speed based on material hardness. For prolonged drilling in hard or stainless steels, use cutting fluid and avoid excessive heat buildup to preserve cutting edge life.
