Drill bit set KREATOR KRT010104 HSS 2.5 x 57 mm — 3 pieces

Three-piece set of HSS twist drill bits KREATOR KRT010104, each 2.5 x 57 mm, designed for general-purpose drilling in metal, wood and plastics. The high-speed steel construction provides strength and heat resistance appropriate for routine workshop and DIY tasks. Straight shank geometry fits standard keyed or keyless chucks, making the set suitable for handheld drills and bench drills used in small repairs and project work.

Advantages

The HSS material retains hardness at elevated temperatures, improving wear resistance during repeated drilling operations. A 57 mm overall length combined with a 2.5 mm drill diameter delivers an effective working length for through-holes and shallow-depth holes in thin materials. Straight shanks ensure secure clamping in common chucks, while the compact three-piece configuration makes it easy to store and replace bits when needed.

Suitable for

• Drilling small-diameter holes in sheet metal and thin plates
• Creating pilot holes in wood and composite panels
• General-purpose repairs and DIY projects
• Hobbyist and light workshop tasks

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 2.5 mm
• Overall length: 57 mm
• Shank type: Straight shank for standard chucks
• Set quantity: 3 pieces

How to use

Install the selected 2.5 mm HSS bit into a properly tightened chuck of a handheld or bench drill. Secure the workpiece with clamps or a vise to prevent movement. Choose a suitable rotational speed for the material: moderate to high speed for wood and plastics, lower speed for steel and harder metals. Apply steady, even pressure and remove chips frequently to avoid clogging. Use cutting fluid or coolant when drilling metal to reduce heat and extend tool life.

Usage recommendations

For best results when drilling metal, use cutting oil and maintain lower speeds to minimize overheating. For wood and plastics, higher speeds and light feed rates produce clean holes. Replace bits when tip wear or chipping reduces hole accuracy; store the set in a dry place to prevent corrosion.
