Drill bit STANLEY HSS-CNC Ø12 mm metal drilling

STANLEY HSS-CNC Ø12 mm metal drilling is a high-speed steel drill bit engineered for drilling precise holes in steel and other ferrous materials. Manufactured from HSS-CNC, this Ø12 mm bit offers the cutting hardness and wear resistance required for workshop, construction and maintenance tasks. It is compatible with drill presses and handheld drills and is intended for applications where dimensional accuracy and reliable metal penetration are needed.

Advantages

The HSS-CNC material provides enhanced edge retention and resistance to heat during continuous drilling operations, helping maintain cutting performance over longer periods. The 12 mm diameter delivers a balance between hole size and structural rigidity for stable drilling. The bit’s geometry is optimized for metal cutting to reduce chatter and improve chip evacuation when used with appropriate cutting speeds and lubrication.

Suitable for

• Drilling holes in mild and alloy steels
• Workshop and industrial metalworking tasks
• Maintenance and repair where precise metal holes are required
• Use with drill presses and handheld electric drills

Key specifications

• Material: High-Speed Steel (HSS-CNC)
• Diameter: 12 mm
• Intended use: Metal drilling (ferrous materials)
• Compatible tools: Drill press, handheld electric drill
• Geometry: Metal-cutting flute design for chip evacuation

How to use

Secure the workpiece and select an appropriate clamping method to prevent movement. Fit the Ø12 mm HSS-CNC drill bit into the drill chuck and tighten firmly. Start drilling at a slow speed to establish the pilot and then increase to a speed suitable for steel, applying steady feed pressure. Use cutting fluid or coolant to reduce heat and prolong tool life, and periodically clear chips from the hole to maintain cutting efficiency.

Usage recommendations

Match drill speed and feed to the specific steel grade: lower speeds for harder materials. Apply cutting lubricant when drilling thicker sections or continuous holes. Inspect the bit regularly for wear and resharpen or replace when cutting performance decreases to maintain hole accuracy.
