Precision Twist Drill 5996362 Letter M Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5996362 is a letter-size M jobber-length drill bit ground from M2 high speed steel with a bronze coating and a 135-degree split-point tip. Sized at 0.2950 inches in diameter, it is designed for general-purpose drilling in production and maintenance environments. The 135-degree web-thinned point self-centers on contact, reducing the need for a center punch on flat stock. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole operations. Machinists, tool-and-die workers, and maintenance technicians are the primary installers of this bit.

This bit is suited for drilling steel, stainless steel, cast iron, superalloys, and titanium in both shop and field settings. It fits standard drill chucks and magnetic drill presses that accept a 0.2950-inch straight cylindrical shank. The 3-1/16-inch flute length supports a maximum drilling depth of 3.0625 inches, making it practical for drilling through typical structural and plate stock. The bronze coating reduces friction and extends service life in ferrous materials. It is a general-purpose replacement bit for letter-M sizing requirements across a wide range of drilling applications.

Installation Notes

Secure the shank fully in a drill chuck or collet before operation. Always match spindle speed to the workpiece material and bit diameter per published HSS cutting-speed tables. Wear appropriate eye protection and secure the workpiece before drilling. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point shows visible damage.
