S-4 Plus SDS

S-4 Plus carbide drill bits are designed for use in a rotary hammer equipped with an SDS (slotted drive shaft) type chuck. The single tip bits are manufactured to conform with ANSI Standard B212.15 and can be used to dril in concrete, block, brick and soft stone. S-4 Plus SDS carbide drill bits are manufactured within a strict tolerance limits for the cutting diameter, the symmetry of the carbide tip to the drill axis, the symmetry of the tip point and the out-of-true variation. The optimal carbide and flute design provides up to 27% faster drilling and extended bit life.
