How To Drill Sea Glass






General Instructions – Tips:

The diamond coating on DRILAX hole saws give superior performance and lifetime. Please note our tools do not need center pilot holes. Center pilot hole drills are mostly for wood, metal, etc.

Regular height Drilax tools can drill 1 inch to 1 1/4 inch depth. We also have the taller version sets with 30% increased depth of cut.

Shank sizes vary but the largest shank is 3/8″ – common electric or rechargeable drillers can be used.

Drilling Speed:

Please see our post on drilling speed.

Electroplated diamond coating will wear off if the tool gets too hot. Never let your drill bit run dry. Here is how you could use water to keep the tool cool:
a- You can build a mini water dam around the hole with plumbers putty.
b- You can choose to spray water on the drill bit.
c- Or you can use running water to cool the drill bit.
Center pilot drill bits are for wood, metal, etc.; Here is how you can keep the drill bit on target:
a- You can make your own guide out of plywood – plastic or even a card board. All you need is to keep the drill bit in place until it makes the initial marks. If you purchased one of sets with the case, the insert will serve as a guide.

b- You can start drilling at an angle, with the edge of the drill bit making a C slot and then getting the drill bit up to vertical.
c- You can manually guide the drill bit with wet sponge

Or you can purchase our innovative adjustable guide for safer operations. Here is how to use the Drilax Drill Guide. 

Please use protective gear.
