Drill bit Proline HSS cylindrical 17.5 mm for metal, model 76175

Proline HSS cylindrical drill bit 17.5 mm is engineered for drilling precise holes in ferrous and non-ferrous metals. Made from high-speed steel, this 17.5 mm metal drill bit provides wear resistance and maintains cutting performance at elevated temperatures. The cylindrical shank design makes it compatible with standard chucks on hand drills and drill presses, supporting common maintenance, fabrication and metalworking operations that require a medium-large hole diameter.

Advantages

The high-speed steel construction offers a balance of hardness and toughness, ensuring longer life during continuous or intermittent drilling in steel, aluminum and other alloys. The cylindrical shank provides reliable gripping in three-jaw chucks and allows quick tool changes. Heat tolerance of HSS reduces the need for frequent cooling pauses, while the 17.5 mm diameter meets specific hole-size requirements without additional reaming for many applications.

Suitable for

• Drilling holes in mild and alloy steels
• Working with aluminum and non-ferrous metals
• Maintenance and repair tasks with portable drills
• Metal fabrication using drill presses
• Preparation of holes for fasteners and fittings

Key specifications

• Material: high-speed steel (HSS)
• Cutting diameter: 17.5 mm
• Shank type: cylindrical
• Suitable for: hand drills and drill presses
• Intended use: drilling in ferrous and non-ferrous metals

How to use

Secure the drill bit in a properly sized chuck, ensuring firm clamping of the cylindrical shank. Select a drilling speed appropriate for the metal type and thickness; lower speeds for hard steels and higher speeds for softer non-ferrous metals. Use cutting fluid or coolant when drilling harder materials or during extended operations to reduce heat and improve chip evacuation. Apply steady, moderate feed pressure and avoid excessive side forces to preserve bit life and hole accuracy.

Usage recommendations

For optimal performance, start with a center punch or pilot mark to prevent walking, and incrementally increase speed and pressure based on material feedback. Use appropriate personal protective equipment and clamp workpieces securely to prevent movement during drilling.
