M35 Cobalt Drill Bit Set, 13-Piece, 1/16-1/4 Inch for Metal - size: 1/16-1/4 inch - 13 PCS - Right Hand

About this item

• 13-Piece Same-Size Pack: Includes 13 matching jobber drill bits, providing convenient replacements for repeated drilling, workshop, fabrication and maintenance tasks.
• M35 Cobalt HSS: Made from M35 high-speed steel with 5% cobalt to support wear and heat resistance during metal drilling when used with suitable speed and lubrication.
• 135-Degree Split Point: The split-point tip helps reduce bit walking and supports controlled starts on flat metal surfaces. A centre punch is recommended for greater accuracy.
• Fully Ground Flutes: Precision-ground twist flutes help move chips away from the cutting edge for smoother drilling. Withdraw the bit periodically to clear accumulated debris.
• Gold Oxide Surface: The gold oxide finish distinguishes the bits while the ground cutting edges support consistent performance during general metalworking applications.
• Straight Round Shank: The conventional straight shank fits compatible keyed and keyless drill chucks, drill presses and bench drills with sufficient chuck capacity.
• For Common Metals: Suitable for stainless steel, steel, cast iron, aluminium alloys and other machinable metals, as well as occasional drilling in wood.
• Use the Correct Settings: Select a slower speed for harder metals, apply steady pressure and use cutting oil to control heat. Excessive speed can reduce bit life.
• Material Limitations: These twist drill bits are not designed for glass, ceramic tile, concrete or masonry. Select a material-specific bit for those surfaces.
• Organised Storage: The included plastic case keeps all 13 bits together, protected and easy to carry between the workshop, garage and job site.
