Drill Bit Set c.k tools T3293 — HSS TiN coated, 6-piece, DIN 338

c.k tools HSS Drill Bit Set T3293 includes six DIN 338 twist drill bits with a titanium nitride (TiN) coating. Manufactured from high-speed steel (HSS) and finished with TiN, the set is intended for routine drilling tasks in metal, wood and plastics. The bits feature a standard point geometry for general-purpose use and are supplied as a compact selection of common sizes to cover workshop maintenance and repair jobs.

Advantages

The TiN coating increases surface hardness and reduces friction during cutting, which improves wear resistance and extends tool life compared with uncoated HSS bits. Precision-ground flutes and a consistent diameter profile ensure reliable chip evacuation and accurate hole sizing. The set format provides quick access to a range of frequently used drill diameters for efficient task completion.

Suitable for

• Drilling holes in mild steel, aluminium and non-ferrous metals
• Woodworking and general carpentry tasks
• Drilling into plastics and composite materials
• Routine workshop maintenance and repair work
• Assembly tasks where matched hole sizes are required

Key specifications

• Material: high-speed steel (HSS)
• Coating: titanium nitride (TiN) for improved hardness and wear resistance
• Standard: manufactured to DIN 338 twist drill geometry
• Set composition: six commonly used drill diameters (general-purpose range)
• Point angle and geometry: standard for general metalworking and multipurpose use

How to use

Select the appropriate drill diameter for the required hole. Secure the workpiece and clamp if necessary to prevent movement. Fit the chosen HSS TiN-coated bit into a suitably rated drill chuck and tighten securely. Use appropriate cutting speed and feed for the material—slower speeds for harder metals, higher speeds for softer metals, wood or plastics. Apply steady pressure; avoid excessive side loads that can break small-diameter bits. Use cutting fluid or coolant when drilling metals to prolong bit life and improve hole quality. Clear chips periodically to prevent clogging.

Usage recommendations

To maximize service life and maintain hole accuracy, use appropriate drilling speeds and lubricants for the material, avoid overheating the bit, and store the bits in a dry, protected case when not in use.
