Drill bit YATO YT-44226 8mm HSS for metal

HSS metal drill bit YATO YT-44226 with an 8 mm diameter is designed for drilling steel and other metallic materials. Manufactured from high-speed steel (HSS), this 8 mm drill bit delivers wear resistance and stable cutting performance suitable for both handheld and stationary drills used in metalworking, maintenance and construction tasks. The tool offers consistent hole accuracy and predictable drilling behavior across a range of common ferrous and non-ferrous metals.

Advantages

The HSS composition ensures good hardness and heat resistance during high-speed drilling, reducing the risk of premature wear. The 8 mm diameter provides a balance between strength and precision for creating medium-sized holes. Ground flutes and a sharpened point enable efficient chip evacuation and reduced walking at drill start, giving more accurate hole placement with less need for pilot holes. The bit’s geometry is optimized for general metal applications, delivering repeatable results with minimal burr formation.

Suitable for

• Drilling holes in mild and alloy steel
• Working with stainless steels of moderate hardness
• Drilling aluminum, copper and other non-ferrous metals
• Maintenance, repair and assembly tasks requiring an 8 mm hole
• Use in handheld electric drills and drill presses

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 8 mm
• Intended material: Metals (ferrous and non-ferrous)
• Tip type: Centered point for general-purpose metal drilling
• Application: Suitable for handheld and stationary drilling machines

How to use

Secure the workpiece and mark the drilling position. Use appropriate clamping to prevent rotation or movement. Fit the 8 mm HSS drill bit into the chuck of a handheld drill or drill press, ensuring it is properly tightened and aligned. Select a suitable rotational speed according to the workpiece material—lower speeds for harder steels and higher speeds for softer metals like aluminum. Apply steady, even pressure and allow the drill bit to cut without forcing. Withdraw periodically to clear chips when drilling deep holes and apply cutting fluid or lubricant when working with harder or heat-sensitive materials.

Usage recommendations

For longer tool life and improved hole quality, use cutting or cooling fluid when drilling steel alloys and stainless steels. Start holes with a center punch to reduce walking, and choose drill speeds appropriate to the material hardness: lower RPM for hard steels, higher RPM for soft non-ferrous metals. Inspect the bit for wear or dulling before use and replace when cutting performance deteriorates.
