Drill bit KREATOR KRT010109 HSS 4.2 mm diameter, 75 mm length

HSS drill bit KREATOR KRT010109 features a 4.2 mm cutting diameter and 75 mm overall length, produced in high-speed steel for general-purpose drilling. Designed for use in metal, wood and plastics, this drill bit is suitable for both handheld drills and drill presses. Its geometry and HSS material balance cutting performance and wear resistance to meet routine maintenance, repair and workshop drilling tasks.

Advantages

The high-speed steel construction offers good hardness and heat resistance for consistent drilling through a range of materials. With a 4.2 mm cutting diameter and a total length of 75 mm, the bit accommodates deeper holes than short bits while remaining compatible with standard chucks. The tip and flute design provide stable cutting and efficient chip evacuation, reducing the risk of clogging during continuous use. The bit is versatile enough for benchwork and field repairs, providing dependable sizing and roundness of holes.

Suitable for

• Drilling holes in thin to medium-thickness metal sheets and profiles
• General-purpose wood drilling for joinery and fittings
• Drilling plastic components and housings
• Maintenance and repair tasks with handheld drills or drill presses

Key specifications

• Cutting diameter: 4.2 mm
• Overall length: 75 mm
• Material: High-speed steel (HSS)
• Intended use: Metal, wood, plastic
• Compatible with: Standard three-jaw drill chucks and drill presses
• Shank type: Cylindrical shank suitable for common chucks

How to use

Secure the drill bit in the drill chuck and tighten firmly to prevent slipping. Select an appropriate drilling speed based on the material: lower speeds for harder metals, moderate speeds for wood and plastics. Use cutting fluid when drilling metals to reduce heat and prolong tool life; for wood and plastics, clamp the workpiece to avoid movement and minimize splintering. Start with a pilot mark or center punch in metal to improve accuracy, then apply steady pressure and allow the bit to cut without excessive force. Withdraw periodically to clear chips when drilling deep holes.

Usage recommendations

Inspect the bit before use and replace if worn or chipped. Store in a dry place to avoid corrosion. When performing repetitive metal drilling, use appropriate cooling and pause to prevent overheating. For precise hole diameters, consider using a pilot or step drilling approach.
