Drill bit Proline HSS straight shank for metal 16.5 mm

Proline HSS drill bit with a straight (cylindrical) shank, 16.5 mm diameter, designed for drilling metal. Made from high-speed steel (HSS), this cutter offers wear resistance and higher heat tolerance during cutting operations. The straight shank allows secure clamping in compatible hand drills and drill presses, making it suitable for workshop and maintenance tasks where holes in steel, iron and other metal workpieces are required.

Advantages

The high-speed steel construction provides a balanced combination of hardness and toughness for reliable performance when cutting metal. The straight shank design ensures stable grip in standard chucks and simplifies changing between tools. A 16.5 mm diameter delivers a precise hole size for applications that need moderate-to-large metal holes while maintaining cutting stability and reduced breakage risk when used according to recommended speeds and feeds.

Suitable for

• Drilling holes in steel and iron components
• Maintenance and repair work in workshops and industrial settings
• Preparation of parts for fastening, assembly or welding
• Use in hand-held drills and bench drill presses with compatible chucks

Key specifications

• Material: high-speed steel (HSS)
• Shank type: straight (cylindrical)
• Diameter: 16.5 mm
• Intended material: metals such as steel and iron
• Typical applications: drilling through solid metal workpieces

How to use

Secure the drill bit in the chuck of a hand drill or drill press, ensuring the straight shank is clamped fully and centered. Select an appropriate cutting speed for the metal being drilled—lower speeds for harder steels and higher speeds for softer metals—and use cutting fluid or oil to reduce heat and extend tool life. Apply steady, even feed pressure and clear chips regularly to prevent clogging. Retract the bit periodically in deep holes to remove swarf and avoid excessive heat buildup.

Usage recommendations

For best performance and longevity, use suitable cutting lubricants, select spindle speeds matched to the workpiece material, and avoid excessive side loads. Inspect the bit for wear or damage before use and replace if the cutting edges are rounded or chipped.
