Which Block Do I Need?

How to Select the Right Core Drill Block

Choosing the right Core Drill Block is easy. 

Each block is made to fit a specific drill barrel diameter - so once you know your measurement, finding the right fit is straightforward.

Step 1: Measure Your Drill Barrel

Most drill barrels have the size stamped on the side - so start by looking there.

If not, use a caliper or measuring tape to check the external diameter. Barrel sizes are typically in millimetres (mm) or inches.

Step 2: Match the Measurement to the Block

Each Core Drill Block is named after the barrel size it supports.

For example:

• • • A 127mm barrel fits a B127 Core Drill Block
    • A 2-inch barrel fits a B2” Core Drill Block

Step 3: Search by Size

Use the search bar to find the block you need - just type in the size (e.g. B127 or B2”). Product listings clearly show the corresponding barrel sizes.
