Review on πŸ”© Bosch HC4021 Speed X Spline Rotary by Philip Lindsey

Revainrating 5 out of 5

Well made slotted drill bit for concrete and masonry

Very strong slotted bit for concrete and masonry. We still use old fashioned (non sds) spline bits and this is a very good buy. Suitable for Bosch/B&D rotary hammers etc. with slots.

Pros
  • Masonry bit
Cons
  • I'll write later
