4mm B1 Push-Type Keyway Broach HSS for CNC Machines – NC

Description

Product Overview

The 4mm B1 push‑type keyway broach is engineered from premium high‑speed steel (HSS) to deliver exceptional wear resistance and dimensional stability even under demanding CNC machining conditions. Designed specifically for the B1 keyway profile, this broach features a precision‑ground cutting edge that maintains consistent geometry across the entire length of the tool, reducing the risk of chatter and ensuring smooth material removal. The tool includes a set of calibrated shims that allow users to fine‑tune the insertion depth, guaranteeing a perfect fit within the machine’s keyway holder and eliminating the need for additional adjustments. With a compact 4mm diameter, the broach is ideal for tight‑tolerance applications where space is limited, yet performance cannot be compromised. Its push‑type design enables quick and secure installation, allowing operators to replace worn tools rapidly, thereby minimizing downtime and maintaining production efficiency. The product is manufactured by NC, a reputable supplier known for delivering high‑quality cutting tools to the industrial sector, and it meets rigorous quality standards that ensure each unit performs reliably out of the box.

Usage

This keyway broach is suited for a wide range of CNC machining environments, including aerospace component fabrication, automotive part production, and precision gear manufacturing. It excels in cutting keyways into hardened steel, stainless steel, and alloyed materials where tight tolerances and clean edges are essential. The tool’s push‑type mechanism simplifies the loading process on standard keyway holders, making it compatible with most CNC machines equipped with a keyway broaching station. Operators can employ the broach for both single‑pass and multi‑pass operations, depending on the material hardness and desired surface finish. For high‑speed production runs, the HSS construction provides superior heat resistance, allowing the tool to maintain its cutting edge without premature dulling. Additionally, the included shims facilitate fine adjustments for varying keyway depths, ensuring optimal engagement and reducing the likelihood of tool deflection. Whether used in a high‑volume manufacturing line or a low‑batch prototyping workshop, the 4mm B1 broach delivers consistent results, making it a versatile choice for engineers and machinists seeking reliable keyway creation.
