High-temp alloys possess poor thermal conductivity and high shear strength, creating a “perfect storm” for tool failure. Heat concentrates directly at the cutting edge rather than dissipating into the chips. Furthermore, these alloys are highly prone to work hardening; if the drill dwells or rubs for even a fraction of a second, the material surface ... Read more

Chip control stainless steel machining is one of the toughest challenges for modern CNC operators. If you ignore chip management, you risk tool failure, poor surface finishes, and dangerous “bird’s nests” that halt production. This guide covers everything you need to know. We will explore geometry, feed rates, and coolant strategies to master this material. ... Read more

There are few sounds in a machine shop more frustrating than the high-pitched screech of a drill bit dying. It’s usually followed by the acrid smell of burning oil and, if you’re unlucky, a puff of smoke that signals your tool has lost its temper—literally. Heat is the enemy of the cutting edge. Whether you ... Read more

Selecting the correct coating for tough materials determines the difference between a profitable job and a scrapped part. When machining hardened steels, superalloys, or cast iron, the tool coating acts as the primary heat shield. It prevents chemical interactions and extends the lifespan of your substrate. This guide compares the top coatings to help you ... Read more

Learning how to drill hardened materials is a challenge that tests even the most experienced machinists and DIYers. If you rush, you will shatter expensive tooling. If you hesitate, the metal work-hardens, becoming nearly impenetrable. I remember my first time trying to drill a broken bolt out of an engine block. I used a standard ... Read more

The most expensive sound in a machine shop is the “pop” of a drill failing deep inside a part. That sound signifies not just a broken insert, but potential damage to the workpiece and the destruction of a drill body often worth hundreds of dollars. Determining exactly how often to change drill inserts in CNC ... Read more

It is the smallest component in the assembly, yet it bears the responsibility of holding back thousands of pounds of cutting force. The insert screw is often the most overlooked variable in indexable drilling. When an insert fails catastrophically, the blame is usually placed on the carbide grade or the speeds and feeds. However, AccurateCut ... Read more

A famous logo doesn’t drill the hole—geometry and physics do. In the machining world, it is easy to default to the “Big Brands” out of habit or perceived safety. However, paying a premium for a marketing budget does not guarantee that the tool is optimized for your specific application. Conversely, buying “budget” drills often leads ... Read more

In the high-stakes world of industrial manufacturing, consistency is king. A drill insert that performs exceptionally well on Monday but fails catastrophically on Friday is a liability, not an asset. For production managers and engineers, finding a supplier is not just about finding the lowest price—it is about finding a partner that guarantees process security. ... Read more
