Letter D corresponds to a diameter of 0.2460 in (6.248 mm), and the Taper Length series provides a longer flute and overall length than jobber drills — typically 4-3\/4 in flute length and 7-1\/8 in overall length for this size — giving added reach for deeper hole applications while retaining a straight shank. The TurboFlute (TurboFL \/ TPR) geometry features a high-helix, parabolic-flute design that dramatically improves chip evacuation, reduces heat buildup, and allows higher feed rates compared to standard twist drills, making these bits well-suited for aluminum, soft steels, plastics, and other materials that generate long, stringy chips. The black oxide finish (steam tempered) provides corrosion resistance and mild lubricity; the bits accept standard drill chucks or collet systems sized for the straight shank diameter matching Letter D. All four pieces are unused and in the original Besly CO-15 packaging.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid
