Drill bit KREATOR KRT010108 HSS 4 x 75 mm

Drill bit KREATOR KRT010108 HSS 4 x 75 mm is a high-speed steel twist drill designed for general-purpose drilling in metal, wood and plastic. The single-piece construction and standard 118° or general twist geometry deliver straight, accurate holes while promoting effective chip evacuation. The 4 mm diameter and 75 mm overall length make this bit suitable for common repair, construction and DIY applications and for use in both handheld drills and drill presses.

Advantages

This HSS drill bit provides good hardness and heat resistance for drilling a range of materials at moderate speeds. Single-piece construction reduces the risk of breakage at the shank-body junction and maintains concentricity for straighter holes. The standard twist flutes enable reliable chip removal, reducing clogging in wood and plastic and improving hole quality in thin metal sheets. The 4 mm diameter is a commonly used size for pilot holes, fastener clearances and general-purpose work.

Подходит для

• Сверление тонколистового и строительного металла
• Сверление древесины и деревянных изделий
• Обработка пластиков и композитов
• Общие ремонтные и монтажные работы
• Использование в ручных дрелях и сверлильных станках

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 4 mm
• Overall length: 75 mm
• Tip/point angle: standard twist geometry (approx. 118°)
• Construction: one-piece solid drill
• Flute type: standard spiral flutes for chip evacuation

How to use

Secure the drill bit in the chuck of a hand drill or drill press, ensuring firm clamping and correct alignment. Select appropriate rotational speed for the material: lower speeds for metals, higher speeds for wood and plastics. Apply steady, moderate feed force and keep the bit perpendicular to the work surface for accurate holes. Use suitable cutting fluid or lubricant when drilling metals to reduce heat and extend tool life; for wood and plastics, drilling is usually dry but controlled chip removal is advised.

Usage recommendations

Before drilling, mark the hole position and, for greater precision in metal, create a small center punch dimple. When drilling deeper holes, periodically withdraw the bit to clear chips and avoid overheating. Replace the bit when wear or dulling is apparent to maintain hole quality and reduce the risk of breakage.
