1PC M2 Step Drill Bit Tungsten-Molybdenum High Speed Steel Nitrided Coating Double Fluted 7/8’’ 1-1/8’’ 1-3/8’’
Sharp tools make good work. With our tungsten-molybdenum high speed steel step drill in hand, you will find drilling holes to be faster and smoother than ever before. The nitrided coating makes the drill bit more durable and last for years with uncompromised quality.
The step drill bit is made from upgraded tungsten-molybdenum high speed steel characterized by well-balanced toughness, wear resistance and red hardness properties for better and faster hole -drilling performance. The nitrided coating makes the drill bit more durable so it can last for years with uncompromised quality.
The X-type flute design prevents metal fillings from flying around and clears chips faster thus it can drill more smoothly without heating up.
The rapid strike tip drills twice as fast as the average step drills and can drill steel plates up to 5mm in thickness.
Thick 3/8-inch hex shank won't round out in the drill chuck for a better grip.
