Draper Expert SDS Auger Drill Bit

The Draper Expert 25mm x 230mm SDS Auger Drill Bit is designed for the most demanding large-diameter drilling applications in all wood types. This substantial 25mm diameter is ideal for major structural timber work, large diameter waste pipes, substantial cable routing requirements, and heavy-duty construction projects where significant hole capacity is essential whilst maintaining drilling precision and control. Manufactured from medium carbon steel and fully hardened, this 25mm bit is precision machined to deliver perfect concentricity even at this considerable diameter. The unique flute spiral incorporates an accurately ground and honed cutting edge along its entire length, ensuring smooth, efficient material removal with reduced effort and minimal binding during operation. The spur tip design provides positive drilling starts and accurate hole placement, whilst the SDS+ shank ensures secure fitment and optimal power transfer for effective drilling performance. Conveniently packed in a hang-up plastic tube for protection and easy storage, this bit delivers professional-grade performance for the heaviest trade applications.
