                                            | Item # 7066, Y-Cutter Head Spline Carbide Drill Bit |  
                                            |  |  
                                            |   |  |  Spline Carbide Drill Bits are designed for use in a rotary hammer equipped with a spline type chuck. The bits are manufactured to conform with ANSI Standard B212.15 and can be used to drill in concrete, block, brick, and soft stone. Both Y- Cutter and single tip head styles are available.
 
 The new Y-Cutter head design has three main cutters in a "Y" configuration which makes up to 32% less noise and vibration compared to the old X-cutting head.
