Alfa Tools Hole Enlarging Drills
Alfa Tools has introduced a complete line of High Speed Steel Core Drills that are ideal for enlarging existing drilled, punched and cast holes in truck frames, structural steel and heavy lattice work. This series of drills includes 11 sizes from 3/8 to 1-1/16 inches in diameter.
The four-flute design provides smooth hole enlarging free from catching and snagging. The Black and Gold Surface treated body and clearance provide lubricity necessary for close tolerance construction work.
All drills have 3 Flats on the shank for safe and secure chucking in standard electric drills.
