66mm High Speed Masonry (HSM) Core Drill Bit CL66S by Armeg

Gives versatility of core drilling from 25 to 110mm diameter. Speeds of up to 35% faster and with minimal breakthrough not normally associated with core drilling. Lightweight, thin wall design, weighing 50% less than traditional core drills, meets less resistance when cutting through masonry materials. More accurate holes can be drilled faster, and breakthrough minimised by drilling on rotation only mode, in softer materials. Great for plumbing and electrical applications in brick, block, masonry, etc. Only for SDS+ or Hex Driven machines.

High Speed Masonry Core can be used in:

• Heavy duty concrete
• General concrete
• Hard bricks
• Soft bricks
• Lightweight blocks
• Natural stone
• Constructional granite
• Limestone

Ideal when working on:

• Waste pipes
• Water feed pipes
• Cable entry / exit
• Flue passage
• Extractor fans
• Exhausts
• Dust extractor ducting

DID YOU KNOW? The HSM range was originally produced in response to greater use of lighter masonry building material where Professional Heavy Duty Core cans be overly powerful. Their popularity rocketed when SDS Plus hammer drills became industry standard.

Technical Tip:-

• When cleanliness of breakout is critical, turn off hammer action and use 'rotary only' mode for the last part of the drilling process

Recommended Speed:-

• Recommended speed for these cores is largely governed by the power tool itself. This is because they are designed to be used in power tools where in the majority of cases there is no facility to regulate the speed (SDS Plus, SDS Max machines etc.).
• If used in a machine where speed regulation is possible, a general recommendation is the larger diameter of the core drill being used, the slower the speed.
