Drill bit set DeWalt DT70745T — 45 pieces, HSS and titanium coated

DeWalt DT70745T — 45-piece drill bit set comprising high-speed steel (HSS) twist drills with titanium coating. The set covers a range of common diameters and is intended for drilling metal, wood and plastics. Titanium coating improves surface hardness and wear resistance compared with uncoated HSS, extending bit life and maintaining cutting performance in general workshop and maintenance tasks.

Advantages

The titanium coating on each HSS bit increases resistance to abrasion and reduces heat buildup during drilling, which helps maintain sharper cutting edges for longer. The set includes a selection of sizes suitable for standard drilling needs, providing versatility for different materials such as mild steel, aluminium, timber and various plastics. Bits are made to common twist-drill geometry for reliable chip evacuation and consistent hole quality.

Suitable for

• Drilling holes in metal including mild steel and aluminium
• Woodworking tasks and furniture assembly
• Plastics and composite panels
• General workshop and maintenance work
• Light industrial and professional use where coated HSS drills are preferred

Key specifications

• Quantity: 45 pieces covering a range of standard drill diameters
• Material: high-speed steel (HSS) with titanium coating
• Drill type: standard twist point geometry for general-purpose drilling
• Intended materials: metals, wood, plastics
• Finish: titanium-coated surface for improved wear resistance

How to use

Select the appropriate diameter for the required hole and mark the drilling position. Secure the workpiece and use a drill press or handheld drill held perpendicular to the surface for best results. Start drilling at low speed to establish the hole, then increase speed according to material and diameter; use cutting lubricant when drilling steel to reduce heat and extend bit life. Apply steady pressure without forcing the bit; clear chips periodically when drilling deeper holes.

Usage recommendations

Inspect bits before use and replace any that are visibly worn or damaged. Store the set in its case to protect the coating and maintain size organization. Use appropriate drilling speeds and lubrication for metal; for wood and plastics, higher speeds and reduced pressure often yield cleaner holes.
