• 【DRILL BIT DIMENSION】: 7/8" (DIAMETER) X 3" (FLUTE LENGTH) X 6" (OVERALL LENGTH)
• 👉 【HSS COBALT MATERIAL】: Cobalt drill bits are known for their durability and ability to withstand high temperatures. The addition of cobalt to the steel helps improve the hardness and heat resistance of the drill bit.
• 👉 【135 SPLIT POINT】: The 135-degree split point is a specific angle at the tip of the drill bit. This design helps to reduce the amount of force required for drilling and minimizes "walking" or drifting of the drill bit when starting a hole. It is particularly useful for drilling into harder materials.
• 👉 【1/2 REDUCED SHANK】: This refers to the diameter of the shank, which is reduced to 1/2 inch. The reduced shank allows the drill bit to be used in a drill press or other machinery with a 1/2-inch chuck.
