Description

What is W Flute 4 Cutter High Stability And Accuracy Hammer Drill Bit?
The W Flute 4 Cutter High Stability And Accuracy Hammer Drill Bit is a specialized rotary hammer bit that features two distinct design innovations: a W-shaped flute and a four-point carbide cutter head.

The W flute design is crafted to maximize dust removal efficiency. Unlike standard straight or U-shaped flutes, the W flute has angular grooves that aggressively channel debris out of the hole, keeping the drilling path clean and minimizing heat buildup. This improves drilling speed and protects the cutting edges from wear.

The 4-cutter head refers to the four symmetrically positioned cutting edges at the bit's tip. This configuration ensures a more balanced impact when drilling, delivering smoother hole entry and reducing the risk of jamming—especially in materials with embedded aggregate or rebar.

Together, these features make the bit exceptionally effective in demanding construction environments, where precision, tool life, and job site efficiency are critical.
