Precision Twist Drill C29M40COSET | 135 Degree Point Angle Bronze Coated Drill Bit Set

Containing 29 fractional drill bits, the C29M40CO drill bit set comes with a sturdy container case, making it easy to transport and keep the drills safe, whilst also keeping them in size order so you can easily select the size you need. The set contains M40CO screw machine length drill bits in sizes from 1/16" to 1/2" in 1/64" increments; 29 drills in total. The drills are manufactured from premium High Speed cobalt, which is suitable for drilling hard materials including tool steel, and come with a bronze oxide finish to prevent workpiece material from sticking to the cutting surfaces of the drill and ensuring an accurate, clean result. As an aid to self-centering, and to reduce the push force required, the drills have a 135 degree split point, whilst the heavy duty design is recommended for use in difficult materials and applications.
