Description

38mm Core Drill Bit 5/8-11

The vacuum brazed core drill bit has a much longer life than conventional drilling (generally 3-5 times), dry drilling without water supply, and the drill bit and wax inside help cool the drill bit. Less debris, minimize breakage, less heat generation, better finishing quality.

• Effectively prevent slipping during drilling and can withstand greater pressure.
• The hole drill bit can be used on power tools such as bench drills, electric drills, and angle grinders.
• Widely used for drilling tiles, granite, marble, quartz, artificial stone, concrete, walls, etc.

When using a core drill bit to drill a hole, first tilt it 45 degrees, find a good position, and drill vertically with the material. Note that the speed should not be too fast, and the speed should be slow.
