Metal drill bit KREATOR KRT011303 HSS 2.5 x 78 mm for metal drilling

HSS straight shank metal drill bit KREATOR KRT011303 with a 2.5 x 78 mm size is made for precise holemaking in a variety of metal materials. Constructed from high-speed steel, this drill bit offers enhanced wear resistance and better heat tolerance compared with standard carbon-steel bits. Its straight shank fits standard chucks on handheld drills and drill presses, making it suitable for both field repairs and workshop tasks where a small-diameter, accurate hole is required.

Advantages

The high-speed steel material provides improved hardness and temperature stability during cutting, which helps maintain cutting edge geometry and prolong tool life. The 2.5 mm diameter enables fine, accurate holes with minimal wandering, while the 78 mm overall length allows drilling through thin plates or reaching slightly recessed areas. The straight shank design ensures secure clamping in common chucks and easy compatibility with collets and drill holders.

Suitable for

• Drilling holes in mild steel, stainless steel, aluminum and non-ferrous metals
• Precision maintenance and repair tasks
• Light fabrication, model making and electronics chassis work
• Use with handheld electric drills and bench drill presses

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 2.5 mm
• Overall length: 78 mm
• Shank type: Straight shank compatible with standard chucks
• Intended application: Metal drilling

How to use

Secure the drill bit in the chuck so the shank is clamped firmly and runout is minimized. Mark the drilling point and, when working on metal, use a center punch to prevent the bit from walking. Select an appropriate cutting speed and feed for the metal being drilled; reduce speed and apply steady pressure for stainless steel and harder alloys. Use cutting fluid or lubricant to reduce heat and improve chip evacuation, retracting occasionally to clear chips when drilling deeper holes. After use, clean off lubricant and store the bit in a dry place to prevent corrosion.

Usage recommendations

For best results, match drilling speed to the material: higher speeds for softer metals like aluminum, lower speeds for harder steels. Apply cutting fluid for extended bit life and cleaner holes. When reaming or enlarging holes, step up diameters gradually to avoid excessive load on the 2.5 mm bit.
