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

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

The Sphinx Drinox Pilot Step Drill delivers up to three times longer tool life, three times higher coolant-through output and three times faster drilling.

The Nirox high-performance drill from SPHINX was developed for use at low cutting speeds in unstable environments.

BIG DAISHOWA introduces the newest addition to its SPHINX micro drill line. The new drill, made of fine-grained solid carbide, delivers exceptional tool life and consistent process reliability.

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

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?

This new micro deep-hole drill from BIG DAISHOWA’s Sphinx line provides a time-saving option for creating wire EDM starter holes, averaging 5X faster per hole according to testing.

Manufacturing miniature parts and features is not new. In the past, EDM and laser technologies were used to create these features. Although these technologies worked for low volume jobs, they are not practical for the high volume micro applications that are in demand today.

Runout can be fickle, but finding a solution for it can pay significant dividends. How a little wobble can really increase your costs.

Many machine shops lack objective criteria for making toolholder purchasing decisions & most are made by price alone. However they can improve runout significantly by using the right toolholders.

The BIG DAISHOWA SPHINX drill series includes more than 2,000 different drills under 3 mm in diameter as standard. With a range of 0.05 to 3 mm diameters.

The medical industry pushes the limits of precision for machining and tools. The trend toward less-invasive surgery using smaller parts translates to a need to better control the preci­sion and tolerances of micromachining processes.

Here are some insights into the extra care and know-how needed to achieve success and build a successful reputation as a reliable supplier of micro machined parts.

Micromachining, cutting where the volume of chips produced with each tool path is very small, is not a high-speed operation in relation to chip load per tooth. Rather, it involves a high spindle speed due to cutter diameter. The part may be physically larger, but details of the part require ultra-small profiles achieved only by micromachining. In other words, micromachining is not limited in scope to only miniature parts.
