Versatile Spot Bit for Centering, Spotting, and Chamfering Steels up to 45 Rockwell C in Canada.
The Snail Tools HRC45 Solid Carbide Spotting Drill is a high-quality tool engineered for precision and reliability when working with general-purpose steels and mild tool steels. Rated for machining up to 45 HRC (Rockwell C), this tool is ideal for accurately defining center points prior to main drilling and for producing clean, precise chamfers. Its robust solid carbide construction ensures exceptional rigidity and minimal deflection, which is critical for achieving tight positional tolerances. Featuring a 5 mm cutting diameter and a standard 5 mm shank, this spot drill is perfectly suited for use in CNC machining centers where accurate spotting and single-pass chamfering are required.
