Milwaukee 48-89-9239 #9 Step Drill Bit, 7/8 to 1-1/8 in Dia, 2-Flute, 3/8 in Dia Shank, 3-Flat Shank

Our line of step drill bits far surpasses the competition. With our single-cutting edge design, you will have more control and a cleaner finish. Made of high-speed steel, these new step drill bits are durable and designed to drill through most metals. The black oxide finish prevents corrosion and has great capacity to work with drilling lubricants. The new speed start tip prevents bit walking and allows faster penetration. With laser etched markings you will always know your hole sizes, no guess work. Finally, the three-flat shank on the largest bit prevents slipping while the 1/4 in hex shank on the two smaller bits allows for fast bit change in impact drivers and sure grip in chucks.Product DetailsManufacturer: MILWAUKEE TOOLManufacturer's Part Number: 48-89-9239Show me more Drill BitsProduct FeaturesBlack oxide finish resists corrosion for longer life3-flat shank prevents bit from slipping in the chuckSingle-cutting edge provides true round holes every timeLaser etched markings for fast, easy hole size identificationSpeed start tip starts fast and reduces the risk of bit walkingProduct Specifications Applicable Materials Aluminum, Brass, Copper, Plastic, Stainless Steel Diameter 7/8 to 1-1/8 in Finish Black Oxide Material HSS Number of Flutes 2 Point Type Speed Start Shank Diameter 3/8 in Shank Type 3-Flat
