Description

The Dry Vacuum Brazed Hex Head Non Core Bits are made to drill in ceramic, porcelain, granite,

marble, quartz,and all natural and engineered stones.

These vacuum brazed drill bits are made to used on Cordless and Electric Drills.The shalft is

hexagon shaped to fit all cordless and electric drills.This keeps the diamond drill bit from spinning

while drilling.

The hex head core bits can be used wet or dry and can be run from 700-6000rpm.

Our Hexagonal shaft diamond drill bit will drill a hole without leaving a core.This is really important

when only drilling into the material without going all the way through.

Before Drilling

Visually examine diamond drill for cracks or any other damage. Do not use if damage is suspected. Damaged, incorrectly mounted, our misused drills can be very dangerous to use. Always wear proper safety equipment: Safety footwear, snug fitting clothing, safety goggles, hearing and head protection,

and proper respiratory equipment. Make sure to check the diamond drill for run out.

Checking Diamond Drill/Bit Run Out

Run out will cause excess vibration when your are drilling and effect the circumference (roundness)

of your hole. Instead of your hole being perfectly round, it will become ellipse and uneven. Diamond Drill/Bit run out will also affect tolerances you are able to achieve. Every diamond drill is made to hold

a specific tolerance and run-out. When ordering diamond drills, make sure to indicate the run-out and tolerance you need. To check for run out, use an indicator specifically designed for this purpose.

Performance

If you smell burning, back off! Either your speed is too high or the pressure you're applying is

too much. You're drill bit should never be hot to the touch, not even warm.

Start your speed off on the lowest setting of your drill. Begin slow and increase as the drill bit

goes through your material. However, ideally keeping a consistently low speed will

prevent your material from cracking and the will help prolong the life of your drill bits.

If the speed is too high this will cause the drill bit to overheat and your material to crack. Plus

the drill bit will become dull quicker, therefore shortening the life of the drill bit.

If the diamonds chip away or fall away from the shank it is probably due to too much pressure -

let the drill do the work and apply very little pressure.

Feel your way through your material. If in doubt, practice on a scrap piece of glass or a garden

pebble until you get used to the technique.

The general rule is the smaller the diameter of your drill bit, the faster drill speed you can use.

The harder your material, the slower drill speed you should use.
