Devgon Industries supplies diamond coring drill bits for stone fabricators and tile installers across Canada. PAUCM is listed for porcelain, porcelain slab, porcelain paver, natural quartzite and Dekton. PAVBDB is listed for marble, ceramic, porcelain and glass. PACBKO is listed for engineered stone and granite. None of these three product listings specifies concrete, masonry or rebar capability.
For porcelain slab work in Toronto or granite countertop fabrication in Brampton, choose the model explicitly listed for your material. All three models are listed for variable speed grinders and dry and wet use. Check the size guide and individual product page for the listed diameters, mount and water-feed guidance.
Request a quote or WhatsApp us to confirm the selected model, material, size, machine compatibility and shipping details.
Choose PAUCM, PAVBDB or PACBKO according to each model's listed materials.
PAVBDB and PACBKO list 5/8"-11 threads. PAUCM lists a variable speed grinder mount; confirm its exact connection.
All three models list dry and wet use, with water-feed guidance on their product pages.
Compare each model's listed diameters and mount in the size guide before ordering.
Use this guide to match a core drill bit to your material, hole size and machine. Every size, mount and material below comes straight from the product listings. Each diamond core drill bit here is listed for a variable speed grinder. Confirm the selected bit's mount and your grinder's compatibility before ordering; a material rating for one model does not apply to the other models.
| Core bit | Diameters | Mount | Engineered for |
|---|---|---|---|
| PAUCM Coring Bit for Ultra Compact Materials | 1/4" (6 mm) – 5" (125 mm) (21 sizes) | Variable Speed Grinder mount | Porcelain, Porcelain Slab, Porcelain Paver, Natural Quartzite, Dekton |
| PAVBDB 5/8 x 11 Threaded Vacuum Brazed Coring Bit | 1/4" (6 mm) – 5" (130 mm) (21 sizes) | 5/8"-11 threaded | Marble, Ceramic, Porcelain, Glass |
| PACBKO 5/8 x 11 T-Slot Coring Bit with Side Protection | 1/2" – 5" (20 sizes) | 5/8"-11 threaded | Engineered Stone, Granite |
PAUCM and PAVBDB each list 21 sizes from 1/4" to 5". PACBKO lists 20 sizes from 1/2" to 5". PAVBDB and PACBKO specify 5/8"-11 threads. PAUCM specifies a variable speed grinder mount but does not state an exact thread. All three specify variable speed grinders; confirm the selected size and connection on the product page before ordering.
None of the PAUCM, PAVBDB or PACBKO listings specifies concrete, reinforced concrete, masonry or rebar capability. Do not use their porcelain, stone or glass ratings as evidence of suitability for those materials. For concrete or reinforced concrete work, use tooling explicitly rated by its manufacturer for the material and machine.
Contact Devgon with your required diameter, material and machine to confirm available options. The current listings do not establish custom-size availability; do not assume an unlisted size or mount is available.
PAUCM, PAVBDB and PACBKO are each listed for dry and wet use. Their product specifications recommend a water feed for sizes under 12 mm. Follow the selected bit's instructions and use water only with equipment designed for wet operation. Wet or dry use does not extend a bit's rating to materials not listed for that model.
Measure the actual outside diameter of the pipe, fitting or sleeve and confirm the required clearance before choosing a listed bit size. First select a model rated for the surface: PAUCM for its listed porcelain, quartzite and Dekton applications; PAVBDB for marble, ceramic, porcelain or glass; PACBKO for engineered stone or granite. These listings do not establish suitability for structural concrete penetrations. Confirm clearance requirements with your engineer, inspector or firestop specification where applicable.
PAUCM requires periodic sharpening. PAVBDB cannot be sharpened. PACBKO does not require periodic sharpening. Follow the selected product's instructions; the listings do not provide a numeric tool-life guarantee or a concrete drilling lifespan.
Share your material, application and equipment to discuss the listed options.
