Power drill accessory set GRAPHITE 56H245 — 7 pcs, steel bits for wood, 220 g, blister

GRAPHITE 56H245 is a 7-piece power drill accessory set designed for drilling and chamfering in wood, engineered plywood, plastics and thin metals. The kit contains two step drills, one adjustable plain drill, three milling drills and a countersink, all manufactured from HSS (high-speed steel) for increased hardness, wear resistance and stability at elevated cutting temperatures. Packaged in a blister with a hardshell case and foam liner, the set weighs approximately 220 g and provides a compact selection of cutting tools for handheld and stationary drills.

Advantages

The set combines step drills for fast hole enlargement, a plain drill for adjustable diameter drilling, small-diameter milling drills for precise pilot and finishing holes, and a countersink for clean chamfers. HSS construction ensures consistent cutting performance, longer tool life and resistance to softening under heat. The included case with foam liner protects tools during storage and transport and keeps the bits organized for quick selection.

Suitable for

• Drilling and enlarging holes in wood and engineered plywood
• Cutting and chamfering in thin metals and plastic panels
• Carpentry repairs, furniture assembly and general DIY tasks
• Use with handheld and bench drills for workshop and home use

How to use

Select the appropriate bit for the required hole size and secure it in the drill chuck according to the drill manufacturer’s instructions. For step drills, start at low speed and apply steady, moderate pressure while allowing the tool to cut progressively through material to reach the desired diameter. For the plain drill and milling drills, mark the drilling point, use a pilot if necessary, and drill at recommended speeds for the material being worked. Use the countersink to produce a clean chamfer or to prepare screw heads; advance slowly to avoid tearing the surface.

Usage recommendations

Use cutting fluid or lubricant when drilling metals to reduce heat and extend bit life. For wood and plastics, adjust drill speed to suit the material and remove chips frequently to prevent clogging. Inspect bits before use for signs of wear and replace if edges are significantly rounded or chipped.
