Dormer E651 UNC Spiral Flute Tap & Drill Set

The Dormer E651 UNC Spiral Flute Tap & Drill Set represents a professional time-saving solution that combines core-hole drilling and tapping operations into a single efficient process. This innovative design eliminates the need for separate drilling and tapping steps, making it ideal for both professional tradespeople working on site and DIY enthusiasts tackling threading projects at home. Available in sizes from No 6 UNC to 5/8 UNC, each set is engineered to produce accurate threads in a single pass.

Manufactured from high-speed steel with a steam-tempered coating, these combination tools deliver exceptional performance when working with steel and cast steel materials. The cylindrical shank features a square drive that allows direct use with standard hand-held power tools, eliminating the need for tap wrenches or time-consuming tool changes between operations. The two-flute spiral design ensures efficient chip evacuation whilst the steam-tempered surface retains lubricant for smoother, more controlled cutting action.
