Draper Expert SDS Auger Drill Bit

The Draper Expert 16mm x 230mm SDS Auger Drill Bit is engineered for larger diameter drilling applications in all wood types, making it ideal for heavier construction work, timber frame installations, and larger pipework or cable management systems. This 16mm diameter provides the capacity needed for substantial fixings whilst maintaining the precision and control expected from the Draper Expert range. Precision machined from medium carbon steel and fully hardened, this 16mm bit delivers perfect concentricity for accurate, wobble-free drilling even at this larger diameter. The unique flute spiral features an accurately ground and honed cutting edge along its entire length, ensuring efficient material removal and preventing binding during operation. The spur tip design guarantees positive drilling starts and prevents wandering, whilst the SDS+ shank provides secure fitment and optimal power transfer from your tool. Supplied in a protective hang-up plastic tube, this bit combines professional-grade construction with practical storage and protection for site or workshop use.
