If you’re looking to get into tight spots with precision, power, and no drama, Everede’s lineup of ANSI boring bars might just be your new best friend in the shop. Whether you're working on small holes, deep bores, or heavy-duty roughing, these tools are built to help you dig deep—and do it right.

Let’s break it down and see what makes Everede’'s ANSI boring bar selection such a solid choice for machinists who want both versatility and reliability.

Boring Bars Built to Go the Distance
Everede isn’t messing around. Their ANSI-standard boring bars cover a massive range, from micro to major. Each series is tailored for a specific type of work, but here’s the quick and dirty:

• Series A – Ideal for micro-machining and tight bores, getting into holes as small as 0.180".
• Series B – A solid step up for light roughing and finishing in bores from 0.270" and up.
• Series C to D – Perfect for general-purpose boring in medium to large diameter applications, up to 1.344".
• Series E through H – These bars give you great flexibility with boring diameters up to 1.094".
• Series FL – Spiral flute? Yes, please. Excellent chip evacuation for clean, consistent cuts in deeper bores.
• Series PB, TH & RCH – Niche bars for specialty cuts and setups—because sometimes your part just has that one weird feature.

Let’s Talk Inserts – Shapes That Get the Job Done
What really brings a boring bar to life? The insert, of course. Everede’s ANSI bars are designed to work with a few go-to insert shapes, and each has its own sweet spot:

• C-Style (80° Diamond, CCGT/CCMT): This is the all-rounder. Great for finishing or medium roughing. The large corner radius makes it stable and forgiving—perfect for general-purpose boring.
• D-Style (55° Diamond, DCGT/DCMT): Think tight corners and fine finishes. D-style inserts are great when you need a sharper angle to avoid walls or features. Expect great chip control and excellent surface finish.
• T-Style (Triangle, TCGT/TCMT): These are tough and aggressive. T-style inserts offer three cutting edges per side and are excellent for more robust applications where material removal is key. Great for cast iron or harder materials.
• W-Style (Trigon, WCGT/WCMT): Your go-to for maximum insert strength. With a wide cutting edge and beefy geometry, W-style inserts handle interrupted cuts or tough materials like a champ.

Everede matches the bar geometry and pocket depth to the insert style, so everything locks in smooth and performs like a dream.

Getting the Right Reach – Length-to-Diameter Ratios
We all know that going too far without the right support can end in chatter and tool failure. Everede’s got you covered with options that balance reach and rigidity:

• Steel Shank Bars: Safe up to about 4:1 L:D ratio. Ideal for shorter reach or shallow depth applications.
• Heavy Metal Shanks: These offer a solid middle ground—typically good for up to 6:1 L:D. The added mass and vibration-damping properties make them great for deeper cuts where chatter can creep in.
• Carbide Shank Bars: These give you extra backbone—up to 8:1 L:D is possible. Best when you're pushing into deeper bores and need maximum rigidity.

Cool Under Pressure – Standard vs. Coolant-Thru
Running dry or flood coolant? No problem. But when the chips are flying and the heat’s rising, Everede’s coolant-thru options are worth their weight in productivity. Keeping the insert cool helps extend tool life, improves chip evacuation, and keeps your tolerances tight.

Why Everede?
Built in the USA and backed by decades of application knowledge, Everede ANSI boring bars are built to last, easy to index, and just plain reliable. Whether you're running a manual lathe, CNC turning center, or tackling aerospace components, there's a boring bar in the lineup that’ll fit your job.

As new materials and technology push the limits of metalcutting performance, threadmaking faces new challenges. From hardened tool steels to exotic super alloys, the demand for tooling capable of threading these materials with precision, speed, and longevity has never been higher. Enter Carmex HBA — a carbide threading grade purpose-built to meet the demands of tomorrow’s toughest materials, available today.

Engineered for the Extreme
Carmex Precision Tools Ltd. developed the HBA carbide grade specifically for hard-to-machine materials like hardened steel up to 62 HRc, cast iron, Titanium, and high-temperature super alloys such as Hastelloy, Inconel, and Nickel-based alloys. At the core of HBA’s performance is its extra-fine submicron carbide substrate, offering high toughness and fracture resistance — crucial properties when threading brittle or abrasive materials.

What sets HBA apart is its optimized combination of substrate, coating, and edge geometry. This triad ensures excellent wear resistance, edge stability, and heat resistance — even under aggressive machining parameters.

Versatility Without Compromise
The HBA grade is available for both internal and external threading, supporting 60° and 55° partial profiles, as well as ISO metric and UN thread standards. This broad compatibility makes it a go-to solution for a range of demanding industries, from aerospace to die and mold, where workpieces often feature heat-treated surfaces or hard coatings.

Proven Performance in Hardened Steel
A recent real-world test highlights the capabilities of the HBA grade. In a threading application on D2 tool steel hardened to 53–56 HRc, a 16 ER 1.5 ISO insert was tasked with cutting an external right-hand thread, M32x1.5, over a length of 65 mm.

Running at a cutting speed of 147.6 SFM (45 m/min) — right in the middle of the recommended 100 to 195 SFM range for hardened materials with the HBA grade — the insert completed the thread profile in just 28 passes. It produced 36 threads per edge, showing not only solid productivity but also the kind of consistency and tool life manufacturers expect when working with high-value, hardened components.

A Solution for Hard Machining
As manufacturers continue to push into hard machining to reduce secondary operations and minimize setup time, the need for robust threading solutions grows. Carmex HBA allows users the ability to hold tight tolerances and maintain good surface finishes even in materials that traditionally pose significant challenges to tool life and performance.

Whether you're threading hardened tool steels in automotive applications or cutting threads in heat-resistant alloys for aerospace components, Carmex HBA offers a solution that blends strength, precision, and reliability.

Challenge Accepted
Carmex invites manufacturers, job shops, and engineers to bring their most difficult threading applications forward. With HBA, complex threading in hard and heat-resistant materials doesn’t have to mean sacrificing speed or tool life. Instead, it’s an opportunity to embrace the next generation of carbide performance — tough, precise, and fast.
