Precision Chamfering Made Easy
Take the guesswork out of deburring and countersinking large-diameter holes with the 82-Degree Indexable Countersink & Chamfer Tool. This robust tool is engineered for professionals, providing a wide 1/2″ to 1-3/4″ capacity from a single 1/2″ shank, making it a versatile addition to any machine shop.
The key to its superior performance is the positive rake cutting geometry. This design ensures a smooth, clean shearing action that significantly reduces chatter, even in tough materials. Unlike traditional countersinks, this tool uses standard carbide inserts, eliminating the need for costly and time-consuming resharpening.
Key Features & Benefits
- Wide Working Range: Efficiently countersinks and chamfers holes from 1/2″ up to 1-3/4″ in diameter.
- Chatter-Free Cutting: The positive rake angle provides a smooth cutting action, delivering a superior surface finish.
- Economical & Efficient: Uses standard SCMT 432 carbide inserts (sold separately), allowing for quick, easy, and cost-effective tool changes. No more downtime waiting for sharpening.
- Robust Design: Features a solid 1/2″ shank for stable and rigid mounting in drill presses, milling machines, and lathes.
- Standard Angle: The 82° included angle is the standard for most common flat head screws in the US.

Cutting Recommendations
- Speeds & Feeds: Start with a low RPM and a steady feed rate. Carbide performs best with a consistent chip load.
- Machine Setup: Ensure your workpiece and the tool are clamped rigidly to prevent any vibration.
- Insert Choice: Use an SCMT 432 insert grade appropriate for your material (e.g., C-6 grade for steel, as seen in our other products).
- Coolant: Applying coolant or cutting fluid will extend insert life and improve the final surface finish.
Frequently Asked Questions (FAQ)
Q: Does this tool come with the carbide insert?
A: This tool holder is typically sold without the insert. It requires one standard SCMT 432 insert, which you can purchase separately from our store.
Q: What is the 82-degree angle used for?
A: The 82° angle is the standard specification for countersinking holes to fit common imperial (inch) flat-head screws.
Q: Can I use this in a handheld drill?
A: This tool is not recommended for handheld use. It is designed for the stability and controlled feed of a drill press, milling machine, or lathe to prevent chatter and ensure safety.
Q: How long does shipping take?
A: We process orders quickly! You can expect your items to be delivered within 3-5 business days.
