Drill Bit for Metal EINHELL 10 mm, model 49258700

EINHELL 10 mm metal drill bit model 49258700 is a single high-speed steel cutting tool designed for creating clean round holes in a variety of metal materials. The bit is intended for use with standard electric or cordless drills and provides a precise 10 mm diameter hole for repair, assembly and fabrication tasks. Its geometry and material composition are suited to drilling through thin to moderate thickness metal sheets, profiles and fastener holes in workshop and DIY environments.

Advantages

The drill bit offers consistent 10 mm hole diameter accuracy and is manufactured to typical heat-treated high-speed steel tolerances for metal cutting. Its point geometry reduces skidding at contact and helps start holes more accurately. The single-bit format makes it easy to carry as a spare in a drill case or tool kit and to replace when worn. Compatibility with standard drill chucks allows straightforward mounting and use with a wide range of portable and bench drills.

Suitable for

• Drilling holes in steel and non-ferrous metal sheets
• Preparing holes for bolts, rivets and fasteners
• Metal repair and assembly work in workshops
• DIY projects requiring a precise 10 mm metal hole

Key specifications

• Nominal diameter: 10 mm
• Material: high-speed steel (HSS) suitable for metal cutting
• Shank type: cylindrical shank for standard drill chucks
• Intended use: drilling in metal sheets, profiles and assemblies

How to use

Secure the workpiece to prevent movement and select a suitable drill with a compatible chuck. Fit the 10 mm drill bit into the chuck and tighten firmly. For improved hole quality and tool life, mark the drilling point with a center punch to reduce wandering, and use a cutting lubricant or coolant when drilling steel. Start at a moderate speed, apply steady pressure, and withdraw occasionally to clear chips. After completing the hole, remove burrs with a deburring tool or file as needed.

Usage recommendations

Use the bit with appropriate personal protective equipment, including safety glasses and gloves. Match drilling speed and lubrication to the specific metal type: lower speeds and cutting fluid for harder steels, higher speeds can be used for softer non-ferrous metals. Replace the bit when wear or chipping reduces cutting performance to maintain hole accuracy.
