3/8" x 5" A-Taper Pilot Drill (5 pack) Vendor: ITM About This Heavy Duty Rotary Hammer Core Bit: Get ready to tackle tough jobs with these Heavy Duty Rotary Hammer Core Bits from ITM. Crafted with special alloy steel and Tungsten Carbide, these bits are designed to endure continuous hammering. Pair them with SDS-Max electric rotary hammer machines along with a pilot drill bit and extension for optimal performance. Specifications: Size: 3/8” x 5" A-Taper Part #: 721PD0385 Instructions: Prep by wiping off oil or lubricant from the taper surfaces. Insert the pilot drill into the drive extension first. Assemble the drive extension into the core bit. Begin drilling until the core bit reaches a depth of 3/8”. Utilize the ejector key to remove the pilot drill. Continue drilling until the core bit is filled with the material, typically at a depth of 3”. If needed, break the drilled material inside the core bit using a chisel. Repeat the process until your desired hole depth is achieved. About Proper Usage: Remember: Always use a pilot drill bit with your core bit to prevent excessive pressure on the shank system. Without it, you risk breakage, especially at the tapered end. Take care of your tools to avoid any unexpected mishaps.
