Selecting the appropriate pilot drill is critical to maximize performance and tool life of a succeeding deep hole or micro drill.

Did you know Sphinx offers 3 unique drill/reamer geometries capable of drilling from a solid while achieving H7-H9 hole tolerance with exceptionally good surface finish?

When using a high-performance drill, we do not recommend turning on coolant until the drill is inside a 1-2xD deep pilot hole.

Customers often get caught in a price war between cutting tool suppliers by attempting to reduce their total upfront investment in tooling.

There’s more than one way to finish a hole. The most effective option will depend on the number of parts, acceptable cycle time and tolerance callouts.

Even among experienced machinists, choosing the right insert for boring a hole remains a difficult process that is fraught with myth and misconception. However, it is no myth that insert selection can completely save or kill performance on an application.

Adjusting screws are not just a simple set screw. They are a screw with a purpose—three actually.

The concept of using guide pins to load large fixtures has been around for a long time, and it even applies when incorporating Unilock zero-point clamping systems in your fixturing.

Did you know you can download 2D and 3D tool data with our Manuals, DXF and Step Search online tool? It is as easy as searching for a catalog number.

Overall gripping strength increases as you increase the size of your tool holders (when looking at the same type of holder).

Reducing the L:D ratio provides an improvement in speed which then provides longer tool life, better surface finish and size control of the bore.

Clamp confirmation for any system, UNILOCK or otherwise, is a sound design criterion when building any workholding system.

When it comes to boring operations, learn when to use a ground chip-breaker vs. a molded chip-breaker.

Sometimes our customers see our tool holder catalog numbers and ask us, "What is BBT and BCV?" Great question!

Cleanliness is key to achieving good runout control when assembling tool holders. Small particles or oil in a tool holder can cause large runout of the cutting tool, deceasing tool life and performance.
