Frequently asked questions
Should I choose dry cores or wet cores?
The product listing will state whether a core is for dry or wet use. Dry cores are for dry core drilling applications in suitable brick, block or masonry materials where stated. Wet cores are for wet core drilling applications in suitable concrete or harder materials where stated on the product listing. Check the individual product data before ordering to confirm the stated material type and wet or dry suitability for your application.
What core diameter should I order?
Match the core diameter to the required opening for the pipework, ducting or cable run. Wet cores from 20mm to 450mm and dry cores from 32mm to 181mm are listed where available. Confirmed wet core diameters in the current range include 62mm, 102mm, 107mm, 112mm and 117mm where listed. Check the project specification and product data before ordering to confirm the correct diameter.
What does barrel length mean when ordering core drills?
Barrel length is the stated length of the core barrel and is a key buying check. Products may be listed at 250mm, 300mm or 450mm barrel lengths. Match the listed barrel length to the project requirement and confirm whether extension bars are needed. Check the product listing and machine compatibility before ordering.
What fittings or thread types should I check before ordering?
Check the fitting or thread type listed on the product before ordering. Wet core products in this range are listed with 1¼" UNC fittings where stated. Accessory fittings include BSP male and female connections and A Taper where listed. If the machine fitting does not match the core or accessory, an adaptor may be needed.
