Notes for wet drilling

• These drills are designed to work with coolant. Insufficient water will shorten the drill life and can result in segment loss with brazed bits.
• When drilling through reinforcement maintain coolant flow & keep steady pressure on the drill bit.
• When using small diameter drills maintain a steady but not excessive pressure as they are not so robust as larger size drills
• Make sure that the rig is securely mounted and in good working order ensuring no excessive play in the rig.

Recommended Water Flow Rates and Operating Speeds

*The above table is a guide to the recommended operational speeds. Other factors such as site conditions, machinery and material being drilled will have an affect on the amount of water needed and the operating RPM.
