Excellent abrasion-resistant sub-brand drill! For screw pilot hole processing and bolt holes!
The "SBLDR/SBLDN/SBLDB-CT" is an optimal subland drill for screw pilot hole processing and bolt hole use. Since the cutting edges are separated into small and large diameters, it is less likely to break during regrinding due to necking at the small diameter outer circumference, and it has excellent regrindability. Additionally, we offer Type A (double margin) which is optimal for screw pilot hole processing, and Type B (single margin) which is optimal for bolt hole processing. 【Features】 ■ Optimal for screw pilot hole processing and bolt hole use ■ Minimal impact from magnetic bite during regrinding ■ Excellent regrindability ■ The grooves for hole processing and chamfering are separated, which helps to separate chips *For more details, please refer to the PDF materials or feel free to contact us.
