Besly Turboflute Drills have heavy duty parabolic profiled flutes for easy chip flow. Designed for automotive, aerospace, and other high volume metalworking industries, they give longer life and better drilled hole quality while allowing increased feed rates. The split point design seats itself and holds centers. Surface treated drills (Catl No. T-705-TF) are intended for drilling stringy, low and medium strength steels below 120,000 psi ultimate tensile strength. Bright finish drills (Catl No. T-755-TF) are for use in aluminum and other nonferrous materials. Also available in sets (Catl No. T-715-TF).

Designed to produce accurate, true centers in all types of screw machine work, to obtain a starting spot for other drills. Short flute and overall length, and no body clearance permits chucking close to the point. Constant web thickness requires no thinning when repointing. Furnished with 118° included angle drill point..

Fractional Sizes

These drills, of very short overall flute length, have been designed for centering work, where their extreme rigidity would reduce runout and eccentricity. For the same reason on larger sizes, they have been quite successful as starting drills in screw machine drilling.
