Employing high-quality alloy steel for the drilling body and YG carbide alloy for the drilling tip, and in combination with various types of electric hammer. The drill is an efficient tool suitably and widely used for hole drilling in hard materials like concrete/brick in the construction & installation industries.
What is L Flute 4 Cutter Wear-Resistant Long Life Hammer Drill Bit?
The L Flute 4 Cutter Wear-Resistant Long Life Hammer Drill Bit is a high-performance rotary hammer bit specially engineered to deliver a longer lifespan, smoother drilling, and cleaner holes in dense, abrasive materials.
The L flute design provides a wider, angular path for removing drilling dust and debris from the hole. Compared to traditional straight or U-shaped flutes, the L-shaped groove reduces clogging and heat build-up, allowing for continuous drilling with less stress on the tool and operator.
The 4-cutter head features four symmetrically placed cutting tips at the bit’s tip, offering a balanced and efficient cutting action. This configuration minimizes bit wandering and increases the bit’s ability to cut through hard aggregates and rebar without jamming or breaking.
The bit’s wear-resistant structure is built to maintain sharpness and strength even after repeated use on high-density materials. This means fewer replacements, lower operating costs, and more consistent performance across demanding jobs.
Together, these features make the L Flute 4 Cutter bit a go-to tool for professional drilling that prioritizes both productivity and precision.
