The negative keyway tolerance allows more control over the size of the cut than conventional end mills, providing a close fit when milling keyways. The two flutes have better chip-carrying capacity than end mills with more flutes while offering additional support when the tool goes deep into the material in applications with a high depth of cut. The 30-degree helix angle supports general-purpose applications. It balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action. The general-purpose TiN coating combines stability at high temperatures with hardness for wear protection, increasing tool life and performance compared to uncoated end mills. (TiN is suitable for a range of materials, but TiCN or uncoated end mills are recommended for machining aluminum.) High-speed steel (HSS) is a common general-purpose steel for cutting tools and is compatible with a variety of materials. The tool’s square end creates sharp, unrounded cuts. The center-cutting design has cutting teeth at the end of the tool, so it can be fed into the workpiece like a drill bit. Cutting diameter tolerance is +0.0000" to -0.0015". The tool has a Weldon shank. End mills are designed to remove material and create multi-dimensional shapes and profiles. They have cutting edges along the outside diameter and flutes that remove chips from the cutting area and allow cooling fluids to enter. If heat is not reduced effectively, the tool’s cutting edges will dull and additional material buildup can occur. The number of flutes can range from two to eight. Two-flute designs offer the most efficient chip removal, but more flutes provide a smoother finish. The shank is the end of the tool held in place by a tool holder or machine. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. Non-center-cutting end mills are for applications such as peripheral milling and finishing, but cannot make plunge cuts. Niagara Cutter has been designing and manufacturing precision cutting tools since 1954. Specializing in end mills, cutting mills, and saws, the company is based in New York and manufactures its tools at facilities in Pennsylvania and Massachusetts. This allows the company control over production, from substrate to coating, which is essential for customers in a variety of industries, especially aerospace and automotive. ## Features - About this item - Keyway tolerance end mills have a negative cutting diameter tolerance that allows more control over the size of the cut than conventional end mills - Two flutes offer better chip-carrying capacity than end mills with more flutes, enhancing the tool’s ability to remove material - Titanium nitride (TiN) is a general-purpose coating that combines high-temperature resistance and increased hardness compared to uncoated end mills - High-speed steel is compatible with a variety of materials - Square nose end mills (also called square end) create sharp, unrounded cuts ## Images ![Niagara Cutter N82070 High Speed Steel Square Nose End Mill, Weldon Shank, TiN Finish, Roughing and Finishing Cutting, 30-Degree, 2-Flute, 2.3125" OAL, 0.219" Cut Diameter, 0.375" Shank Diameter - Image 1](https://images-na.ssl-images-amazon.com/images/I/71eWt4v03yL.jpg) ![Niagara Cutter N82070 High Speed Steel Square Nose End Mill, Weldon Shank, TiN Finish, Roughing and Finishing Cutting, 30-Degree, 2-Flute, 2.3125" OAL, 0.219" Cut Diameter, 0.375" Shank Diameter - Image 2](https://images-na.ssl-images-amazon.com/images/I/617nOkclQzL.jpg) ![Niagara Cutter N82070 High Speed Steel Square Nose End Mill, Weldon Shank, TiN Finish, Roughing and Finishing Cutting, 30-Degree, 2-Flute, 2.3125" OAL, 0.219" Cut Diameter, 0.375" Shank Diameter - Image 3](https://images-na.ssl-images-amazon.com/images/I/71oaY1fJQfL.jpg) ![Niagara Cutter N82070 High Speed Steel Square Nose End Mill, Weldon Shank, TiN Finish, Roughing and Finishing Cutting, 30-Degree, 2-Flute, 2.3125" OAL, 0.219" Cut Diameter, 0.375" Shank Diameter - Image 4](https://images-na.ssl-images-amazon.com/images/I/614Nm2PAyML.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent *by W***D on Reviewed in the United States on August 11, 2018* Sharp and durable. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/121381993-niagara-cutter-n82070-high-speed-steel-square-nose-end-mill](https://www.desertcart.vu/products/121381993-niagara-cutter-n82070-high-speed-steel-square-nose-end-mill) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
