![]() ![]() It is important to push only with enough force to keep the bit from bouncing. The bit will rotate and impact at the same time. The hammer drill should only be used in the hammer/rotation position when using a Spline bit to drill into concrete. The spline bit is placed into the end of the drill and is held in place with a retaining pin that engages just below the spline section of the shank. Spline bits are designed for use with a rotary hammer drill with a spline drive. Spline drill bits are held to exacting tolerances to assure a perfect fit as well as maximum impact and torque transmission. Spline drive hammer bits are milled from a single piece of steel to provide maximum life. The carbide is brazed onto the head to harden the tip of the spline bit to assist in the breaking of the concrete. The head and carbide tip: These 2 parts work together to break up the concrete.The flute facilitates the removal of the concrete dust as the hole is being drilled. The flute: This can also be considered the trough section of the spiral.The land: The land is the raised portion of the spiral (similar to the crest or peak of a wave).These shank bits are held to exact tolerances to assure a perfect fit into the hammer drill. The shank: The spine hammer bit has 12 "teeth", or splines that fit into the hammer drill collar.Spline hammer bits are made up of 4 distinct parts. The spline hammer bit gets its name because it has a spline shank (meaning it has 12 "teeth") that fits into the spline drive of the hammer drill. The bit one chooses to use for this purpose is typically dependent upon the type of hammer drill being used. When a post-installed concrete anchor is being used to attach a fixture to cured concrete, a hole must be drilled in the concrete. Purchase Spline Bits What is a Spline Bit? ![]()
