Högert Technik Metal Drill Bit 8.5 mm, Split Point, 5 Pieces

The Högert Technik metal drill bit set includes five high-quality 8.5 mm bits engineered for precision and durability in demanding metalworking environments. These drill bits feature a specialized split point tip, which significantly improves centering accuracy and reduces the amount of pressure required during the drilling process. Constructed to meet professional standards, these tools provide consistent performance and longevity when working with a variety of metallic materials.

Advantages

The primary benefit of these drill bits is the split point geometry, which eliminates the need for center punching and prevents the bit from walking across the surface of the material. This design feature ensures cleaner, more accurate holes while reducing wear on both the drill bit and the power tool. The robust construction ensures high resistance to thermal stress and mechanical deformation, making them a reliable choice for repetitive drilling tasks in industrial or workshop settings.

Suitable for

• Drilling in structural steel and carbon steel
• Working with cast iron components
• Processing non-ferrous metals such as aluminum, copper, and brass
• General metal fabrication and repair tasks

When it may not be suitable

These drill bits are specifically optimized for metalworking and may not provide optimal results when used on masonry, concrete, or hardened ceramics. Using them on materials significantly harder than the bit material may lead to rapid dulling or breakage.

Key specifications

• Diameter: 8.5 mm
• Tip geometry: Split point
• Quantity: 5 pieces
• Material compatibility: Steel, cast iron, non-ferrous metals

How to use

To achieve the best results, ensure the drill bit is securely fastened in the chuck of your power drill or drill press. Mark the drilling location if necessary, although the split point design minimizes the need for pre-drilling. Apply steady, moderate pressure and maintain a consistent speed appropriate for the material being drilled. It is recommended to use a cutting fluid or lubricant to reduce friction and heat buildup, which will extend the lifespan of the drill bits.

What to consider before purchase

• Verify that your drill chuck supports an 8.5 mm shank diameter
• Ensure the material hardness is compatible with high-speed steel tools
• Consider the required drilling depth for your specific application

Usage recommendations

Always wear appropriate eye protection when drilling metal to prevent injury from flying chips. Regularly inspect the cutting edges for signs of wear and sharpen or replace the bits if performance decreases to maintain hole quality.
