Drill bit HSS YATO YT-44218 4.8 mm

HSS twist drill bit YATO YT-44218 with a nominal diameter of 4.8 mm is designed for creating precise holes in metal, wood and plastics. Manufactured from high-speed steel, this drill bit offers consistent cutting performance and increased wear resistance compared with standard carbon-steel bits. The straight shank fits standard chucks of handheld and stationary drills, enabling easy mounting and stable operation for general repair, construction and DIY tasks where a 4.8 mm hole is required.

Advantages

The high-speed steel (HSS) construction provides improved hardness and elevated heat resistance during sustained drilling. The twist geometry ensures efficient chip removal and reduced clogging when working through different materials. A consistent 4.8 mm diameter and precision ground flutes contribute to accurate hole size and straight drilling. The straight shank design is compatible with most three-jaw and keyed chucks, simplifying tool changes and ensuring a secure fit.

Suitable for

• Drilling through mild steel, sheet metal and non-ferrous metals
• Woodworking tasks requiring accurate 4.8 mm holes
• Plastic components and acrylic panels
• Handheld drill and drill-press operations
• Repair, maintenance and small-scale construction jobs

• Diameter: 4.8 mm
• Shank type: Straight shank for standard chucks
• Tip style: Twist drill geometry for general-purpose drilling
• Intended materials: Metal, wood, plastics
• Typical applications: Handheld and stationary drilling

How to use

Secure the drill bit in the chuck and tighten according to the drill manufacturer's instructions. Select an appropriate spindle speed for the material being drilled—moderate to higher speeds for wood and plastics, lower speeds for metals—to reduce heat and preserve cutting edge life. Use steady, moderate feed pressure and allow the bit to cut without excessive force. For metal drilling, apply cutting fluid or lubricant to extend tool life and improve chip evacuation. Retract periodically on deep holes to clear chips and prevent clogging.

Usage recommendations

Inspect the drill bit for visible wear or chipping before use and replace when accuracy or cutting performance declines. Store in a dry place and keep the cutting edges clean. For repetitive metal drilling, use appropriate coolant and controlled feed to maximize service life. When drilling thin sheets, support the workpiece to minimize burrs and prevent deformation.
