Product features:
1. ldeal for both dry and wet work when making pass-through penetrations in wide range working conditions including engineering and concrete.
2. The unique "Helix" barrel design draws dust down the barrel.
3. Dry work is allowed for brick, block and other masonry applications.
4. For hard materials like reinforced concrete, wet use only.
Our handheld core drill comes with a core bore drill, a pilot bit, and a hot-pressed corrugated saw blade, well-designed to furnish you with maximum convenience.
High-frequency welding has firm, sharp, and wear-resisting properties, the heat evenly technique without missing welding.
The core drill reducer is paramount to your projects, widespread used in installing air conditioning, range hood, sewer, and engineering coring.
