VMD Drill
Diameter:Φ45mm~180mm
Effective length: Diameter adjustable

*Adopts a center pilot drill structure with good centering effect and high hole position straightness.

*The inner and outer insert adopt a replaceable cutter holder structure. In actual use, the outer insert tool holder is the most easily damaged. By replacing the small tool holder, the entire drill bit can be avoided and tool costs can be saved.

*The cutter head and cutter holder adopt a combined structure. To process holes of different depths, just replace the tool arbor with different lengths.

*The entire drill bit has a central water outlet, which can better cool the insert and increase the service life of the insert. Internal cooling is more conducive to the discharge of iron filings.

*The inserts are hardened alloy standard products, which can use higher speeds and feeds. The hole wall finish is also significantly improved compared to high-speed steel drills.

* During the machining process, the iron chips are in a broken state, and there are no slender winding iron chips of traditional twist drills, which greatly improves safety.

*During the machining process, the tool is automatically and continuously fed, eliminating the need to push the tool back every time, greatly improving efficiency.
