Dormer A110 Series HSS Twist Drill Bit, 1mm Diameter, 56 mm Overall

When shallow holes won’t cut it, reach for this drill bit from Dormer. It has an overall length of 56mm and a flute length of 33mm, so it's ideal for drilling through multiple layers of substrate. A conventional 118° point angle reduces the risk of wandering while ensuring it's sharp enough for either handheld or machine drilling. Its steam-tempered finish means it resists wear for a long service life.

• Slim diameter of 1mm means it's ideal for drilling pilot holes
• HSS material resists corrosion, heat and impact

• Metalworking
• Factory automation
• Automotive manufacturing
• Woodworking
• Home repairs

For optimal performance, be sure to use lubricant when drilling through thick or tough materials to ensure smooth performance and prevent wear.
