Material: High Speed Steel Coating: Titanium coated Compatibility: Fits hole sizes 2-5 mm, 5-10 mm, 10-15 mm, 15-20 mm Key benefits - Durable cutting edge: High Speed Steel provides toughness and long life for metalworking tasks. - Reduced wear and heat: Titanium coating lowers friction and heat buildup, extending tool life and maintaining cutting quality. - Versatile sizing: Designed to work across four common diameter ranges, enabling multiple hole sizes with a single tool. Performance and use - Delivers reliable drilling performance with consistent results across the specified size ranges. - Suitable for general workshop tasks and metal fabrication where holes in 2–20 mm are required. Use scenarios - Drilling small to mid-size holes in metal sheets or profiles (2–5 mm, 5–10 mm). - Creating larger holes in brackets or steel components (10–15 mm, 15–20 mm). - Value-added projects and repairs in a home or professional workshop where multiple hole sizes are needed without changing tools.
