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.
