Drill bit GRAPHITE HSS cylindrical 10 mm (model 55H033)

GRAPHITE HSS cylindrical drill bit 10 mm (model 55H033) is a high-speed steel tool intended for drilling metal. Its cylindrical shank and 10 mm diameter make it suitable for use in drill presses and handheld drills, delivering precise through-holes in ferrous and non-ferrous metals. The HSS material offers improved cutting performance and resistance to wear during standard workshop and maintenance operations.

Advantages

The HSS construction provides hardness and heat resistance for effective metal cutting at moderate speeds. The cylindrical shank ensures compatibility with standard chucks and simple mounting, while the 10 mm diameter offers a common size for fabrication, repair and assembly tasks. The geometry of the cutting edges is optimized for stable drilling and reduced vibration when used with appropriate feeds and speeds.

Suitable for

• Drilling through mild steel, stainless steel, aluminium and other non-ferrous metals
• Workshop fabrication and general metalworking
• Maintenance, repair and installation tasks
• Use in drill presses and handheld drills for creating precise through-holes

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical shank for standard chucks
• Diameter: 10 mm
• Tip/point: General-purpose cutting geometry for metal drilling
• Typical applications: Ferrous and non-ferrous metals

How to use

Secure the drill bit in the chuck ensuring the shank is fully gripped and concentric. Select an appropriate rotational speed and feed rate for the metal being drilled; use lower speeds for harder metals and higher speeds for softer materials. Apply steady pressure and allow the bit to cut without excessive force. Use cutting fluid or coolant when drilling steel to reduce heat and prolong tool life. After drilling, remove swarf from the hole and inspect the drill bit for wear or damage before further use.

Usage recommendations

For best results, match speed and feed to the workpiece material and maintain proper lubrication when drilling steel. Replace the drill if cutting becomes inefficient or if the point is damaged; regrinding is possible if appropriate equipment and skills are available.
