The Milwaukee HSS-R metal drill bit set consists of 10 high-quality bits, each with a diameter of 6.8 mm. These tools are engineered for reliable performance when drilling into steel, cast iron, and various metal alloys. Featuring a robust rolled flute design, these drill bits facilitate efficient chip removal, which helps maintain cooler operating temperatures and extends the overall service life of the tool during demanding drilling operations.
Advantages
These drill bits are manufactured to provide consistent results in professional metalworking environments. The rolled flute geometry is specifically optimized to reduce friction and prevent clogging, allowing for smoother penetration into hard materials. Their durable construction ensures that they maintain structural integrity even under continuous use, making them a dependable choice for both workshop and construction site applications.
Suitable for
- Drilling into steel and cast iron
- General metalworking and fabrication
- Construction and maintenance tasks
- Creating precise holes in metal alloys
When it may not be suitable
These bits are specifically designed for metal applications and may not provide optimal results when used on masonry, concrete, or extremely hard materials like hardened stainless steel or ceramics. For such materials, specialized carbide-tipped or cobalt drill bits are recommended.
Key specifications
- Diameter: 6.8 mm
- Material: HSS-R (High-Speed Steel, Rolled)
- Quantity: 10 pieces
- Design: Rolled flute for chip removal
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 point clearly to ensure precision. Apply steady, moderate pressure while maintaining a consistent drilling speed appropriate for the metal being worked on. It is recommended to use a cutting fluid or lubricant to reduce heat buildup and prolong the sharpness of the cutting edges.
What to consider before purchase
- Verify that your drill chuck supports a 6.8 mm shank diameter
- Ensure the material you are drilling is compatible with HSS-R steel
- Consider the need for cutting oil to improve performance
Usage recommendations
Always wear appropriate eye protection and safety gear when operating power tools. Regularly inspect the drill bits for signs of wear or dullness and replace them as necessary to maintain drilling efficiency and safety.
