Metal drill bit YATO YT-4100 10.0 mm HSS for drilling metal

YATO YT-4100 10.0 mm HSS metal drill bit is engineered for precise drilling in steel and a variety of other metals. Manufactured from high-speed steel (HSS), this 10.0 mm diameter bit balances hardness and toughness to resist wear and retain cutting performance under elevated temperatures common in metalworking. The geometry of the tip and flutes enables stable chip evacuation and consistent hole quality when used in hand drills or drill presses.

Advantages

The HSS material offers improved heat tolerance compared with standard carbon-steel bits, reducing the risk of tempering during continuous use. The 10.0 mm diameter provides a common, versatile size for mechanical assembly, fabrication and maintenance. Ground cutting edges ensure accurate centering and reduced walking at the start of a hole, while the flute design supports efficient chip removal to maintain cutting efficiency and extend tool life.

Suitable for

• Drilling through mild and medium carbon steel
• Creating holes in stainless steel and non-ferrous metals (with appropriate speeds and lubrication)
• Workshop fabrication and on-site repair tasks
• Use with hand-held drills and bench or pillar drill presses

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 10.0 mm
• Tip type: standard split or ground point for accurate centring
• Shank: round shank compatible with standard drill chucks
• Suitable for use with cutting lubricant when machining harder alloys

How to use

Secure the workpiece to prevent movement and select appropriate rotational speed for a 10.0 mm HSS bit—lower speeds for harder steels and higher speeds for softer metals. Fit the drill bit into the chuck and ensure it is held straight and tight. Apply steady feed pressure and allow the drill bit to cut without excessive force; withdraw occasionally to clear chips if necessary. Use cutting fluid when drilling stainless steel or other high-strength alloys to reduce heat and improve tool life.

Usage recommendations

Maintain proper speeds and lubrication, replace the bit when wear affects hole quality, and store in a dry place to avoid corrosion. For optimal results in very hard or abrasive materials consider using coated or carbide drills designed for those applications.
