HSM High Speed Masonry Core Drills

A rapid action core drill ideally matched to SDS Plus Machines 

Perfect for Brick and Blockwork Drilling!

• Speeds of up to 35% faster and with minimal breakthrough not normally associated with core drilling. Lightweight, 2.5mm ultra thin wall design, weighing 50% less than traditional core drills, means 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. Suitable for SDS+ or Hex Driven machines.
  
• Unique Armeg original design ball-locking & pilot drill system eliminates the need for awkward grub screws, meaning pilots and arbors can be interchanged quickly for greater convenience
• Precision machined arbor flats allow users to easily use grips or a spanner to lock on to the arbor for easy separation of core assembly
• Ultra hard tungsten carbide tips provide increased wear resistance allowing users to operate the core on 'hammer action' for rapid drilling speeds.
• Machined Tommy Bar hole allows users to locate a Tommy Bar for hassle free disconnection of arbor and core drills.

• Heavy duty concrete 
• General concrete
• Hard bricks
• Soft bricks - Very sutiable
• Lightweight blocks - Very suitable
• 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

Tech-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.
