Precision Twist Drill 1-17/64-2FL-MT4-135 Drill Bit

Precision Twist Drill 1-17/64" diameter, 2-flute drill bit with a Morse taper 4 (MT4) shank and a 135° point angle. The two-flute geometry provides efficient chip evacuation and improved rigidity when drilling large-diameter holes in metalworking tasks, helping maintain alignment through the hole. The 135° tip angle offers a sharp, stable entry into the workpiece with reduced walking at start of penetration. The MT4 shank interfaces with Morse-taper toolholders and spindles designed for MT4 tooling, making it compatible with drill presses and milling machines configured for MT4 bits. This bit’s defined bore size is 1-17/64", making it suitable for applications that require a precise, large-diameter hole in metal; verify your machine’s MT4 interface and select appropriate speeds and feeds for the material being drilled.
