Product Engineering
Built for Clean Holes in Hard Decorative Materials
BK-9091 combines a rigid nickel-plated steel cup with an electroplated diamond cutting rim. The open-core design is intended for water-cooled drilling where edge quality and controlled material removal matter.
Coolant & Debris Slots
Elongated side openings support water circulation, chip discharge and core removal.
Machined Round Shank
Straight-shank structure fits standard drill chucks; shank dimensions vary by product size.
Wide Size Coverage
The 3-200mm diameter range supports fine glass work, installation and large project openings.

Application Scenarios
Wet Drilling for Glass, Tile and Stone
The electroplated rim should face the material. Keep the cutting area supplied with water and use a stable guide for large diameters.
Tool Compatibility
Match the Tool to the Diameter
Use a standard electric drill, drill press or dedicated glass drilling equipment. Do not use hammer mode. Large diameters require more stable guidance and sufficient coolant.
D
Electric Drill
Suitable for controlled handheld wet drilling with a guide or angled start.
P
Drill Press
Improves vertical alignment, feed control and repeatability for workshop use.
W
Water Cooling
Continuous coolant reduces heat, clears abrasive debris and supports edge quality.
0
No Hammer Mode
Use rotary drilling only; impact action can damage glass and brittle surfaces.
Recommended Workflow
Four Steps for Controlled Wet Drilling
- 01Secure the WorkpieceSupport the material and mark the hole location.
- 02Guide the EntryUse a drilling guide or begin with a controlled angled contact.
- 03Keep Water FlowingMaintain coolant at the rim throughout drilling.
- 04Use Light FeedLet the abrasive cut; avoid excessive pressure and impact.
