Meet the next generation of Needle D's.
We took our three precision diamond bit sizes and rebuilt the setup around the tool tile installers already have in their hands all day:
The grinder.
Instead of a 1/4" quick-change connection, the new Needle D's feature a 5/8"-11 threaded connection that mounts directly onto a compatible angle grinder.
That means more RPM, more control and no adapter or quick-change holder required.
Each bit also features a wax-packed core to assist with cooling while drilling.
And instead of choosing individual sizes, we're giving you all three.
6MM. 8MM. 12MM.
One set.
THREAD 'EM ON. SEND 'EM.
The smallest Needle D in the set.
Built for small, precise penetrations where accuracy and control matter.
The middle ground.
A versatile small-diameter bit for professional tile drilling and everyday installation work.
The largest Needle D.
Gives you the same direct-thread grinder setup when the job calls for a larger 1/2" opening.
6MM • 8MM • 12MM
No choosing.
No individual sizes.
You get all three.
This is the big change.
Traditional Needle D's used a 1/4" quick-change connection.
The new Needle D's feature a 5/8"-11 threaded connection designed to screw directly onto a compatible standard angle grinder spindle.
Why?
A grinder gives these small diamond bits the speed they want to work efficiently.
The grinder setup gives the installer excellent control over the bit while starting and completing the opening.
No quick-change holder.
No separate adapter.
Thread the Needle D directly onto your compatible grinder and get to work.
Small diamond bits can generate serious heat.
That's why each Needle D comes with a wax-packed core designed to assist with cooling during drilling.
As the bit works, the wax provides additional cooling assistance where the heat is being generated.
It's another feature designed specifically around getting better performance from these small-diameter diamond bits.
Small holes leave very little room for error.
Needle D's give you three precision sizes for drilling clean penetrations through hard tile materials.
Great for:
Porcelain tile
Ceramic tile
Granite
Marble
Compatible natural stone
Small plumbing penetrations
Fixture mounting
Hardware penetrations
Anchor locations
Professional tile installation
Because the hole you need on this job might not be the hole you need on the next one.
Rather than selling the new Needle D's individually, we're putting the three core sizes together.
6mm / 1/4"
8mm / 5/16"
12mm / 1/2"
Keep the set in your bag and grab the size the installation calls for.
Don't let the size fool you.
These little D's are designed around the speed and control of your angle grinder.
Direct 5/8"-11 thread.
Higher RPM.
Wax-packed cooling assistance.
Three precision sizes.
That's a whole lot packed into a little bit.
1 × 6mm / 1/4" Needle D
1 × 8mm / 5/16" Needle D
1 × 12mm / 1/2" Needle D
