Tungsten carbide core drill can be a cost effective means of drilling through softer unconsolidated formations. And such a core drill is applicable to hole cutting and process of annular groove on various magnetic drills and press. Tungsten carbide does not possess the hardness of diamond, while it is relatively cheap compared with diamond drill. It cuts effectively at low r.p.m. (revolution per minute) and low weight on bit.

Tungsten carbide core drill has selected special-purpose carbide tips with multi-cut geometry for ply-cutting and lower friction. Also, the core frill has reduced damage of tips and improved performance of chips removal. And it has more stable clamping for stable cutting and finish of holes. The major benefit of tungsten carbide drill bits is that they provide a longer working life due to their hardness factor. Hardened steel is not able to last as long in steady applications as tungsten carbide. By utilizing tungsten carbide material, industries can keep their drill bits on line in the field for longer periods of time preventing down time and loss of time spent on a project.
