Drill Bit YATO Urbis Metal Co-HSS 16 mm YT-4160

YATO Urbis Metal Co-HSS 16 mm YT-4160 is a twist drill bit designed for precise drilling in steel and other metal materials. Manufactured from cobalt-alloy high-speed steel (Co-HSS), this 16 mm diameter bit provides increased wear resistance and improved heat tolerance compared with standard HSS drills. The geometry and material of the cutting edges make it suitable for both hand-held drills and drill presses commonly used in workshops, maintenance and fabrication environments.

Advantages

The cobalt-alloy Co-HSS construction reduces flank wear and maintains cutting performance at higher temperatures, extending tool life during continuous or demanding drilling operations. The 16 mm diameter offers a balance between rigidity and material removal rate, while the twist-flute design ensures efficient chip evacuation. Compatible with common drill chucks and mounting systems, the bit delivers consistent round holes and reliable centering on ferrous and non-ferrous metal workpieces.

Suitable for

• Drilling through mild and alloy steels
• Fabrication and metalworking tasks in workshops
• Maintenance and repair operations requiring metal hole-making
• Use with hand drills and drill presses for through-holes and pilot holes

Key specifications

• Material: cobalt-alloy high-speed steel (Co-HSS)
• Diameter: 16 mm
• Type: twist drill bit for metal
• Flute design: spiral twist for chip evacuation
• Suitable for: ferrous and non-ferrous metals

How to use

Secure the bit in the drill chuck and ensure the workpiece is properly clamped. Select an appropriate cutting speed and feed rate for the material being drilled; lower speeds are recommended for harder alloys to reduce heat buildup. Apply steady pressure and allow the drill to cut without excessive force. Use cutting fluid or lubricant when drilling thicker sections or harder steels to improve cooling and chip evacuation. After drilling, withdraw the bit while the spindle is still turning to clear chips from the hole.

Usage recommendations

For best results, match drill speed and coolant to the metal grade: use moderate speeds and suitable cutting fluid for stainless and high-alloy steels, and higher speeds for softer, low-carbon steels. Inspect the bit for wear and regrind or replace when edge rounding or chipping is observed to maintain hole quality and safety.
