Irwin HSS Cylindrical Drill Bit 19.5mm

The Irwin HSS cylindrical drill bit, with a diameter of 19.5mm, is a high-performance tool engineered for precision drilling in metal and various other materials. Constructed from high-speed steel, this drill bit offers excellent heat resistance and durability, ensuring consistent performance during demanding drilling operations. Its standard cylindrical shank design allows for seamless integration with most standard power drills and drill presses, providing a reliable solution for both professional metalworking and general construction projects.

Advantages

This drill bit stands out due to its robust high-speed steel construction, which maintains sharpness and structural integrity even under high-friction conditions. The precision-ground geometry ensures accurate hole placement and efficient chip removal, which helps prevent overheating and extends the overall service life of the tool. Its universal compatibility with standard chucks makes it a versatile addition to any workshop, reducing the need for specialized equipment.

Suitable for

• Drilling holes in steel and iron
• General metalworking and fabrication
• Construction and maintenance tasks
• Drilling into non-ferrous metals and plastics

When it may not be suitable

This drill bit is not intended for drilling into hardened steel, masonry, concrete, or stone, as these materials require specialized carbide-tipped bits. Using this high-speed steel bit on such surfaces will lead to rapid dulling and potential damage to the cutting edges.

Key specifications

• Diameter: 19.5mm
• Material: High-speed steel (HSS)
• Shank type: Cylindrical
• Application: Metal and general materials

How to use

To use the drill bit, ensure it is securely tightened in the drill chuck. Mark the center point of the hole to be drilled and use a center punch to create a small indentation, which will prevent the bit from wandering. Apply steady, moderate pressure while maintaining a consistent drilling speed appropriate for the material being worked on. It is recommended to use a suitable cutting oil to reduce friction and heat buildup during the drilling process.

What to consider before purchase

• Verify that your drill chuck capacity can accommodate a 19.5mm shank diameter.
• Ensure the material you intend to drill is compatible with high-speed steel tools.
• Consider the thickness of the material to ensure the drill bit length is sufficient.

Usage recommendations

Always wear appropriate eye protection and safety gear when operating power tools. Regularly inspect the drill bit for signs of wear or damage and sharpen or replace it as necessary to maintain optimal performance.
