Woodruff Keyseat Cutter Moon Cutter KY650 3/4″ Dia 1/2″ Shank

Description

Product Overview

The Moon Cutter Woodruff Keyseat Cutter KY650 is a precision‑engineered milling cutter designed for demanding industrial and scientific applications. Constructed from high speed steel (HSS), the cutter offers exceptional hardness and wear resistance, ensuring a long service life even under heavy cutting loads. With a 3/4 inch (19 mm) cutting diameter and a 1/2 inch (12.7 mm) shank, the tool balances rigidity and flexibility, allowing it to handle a wide range of materials from hardwoods to soft alloys. The cutter features ten flutes, a design that promotes efficient chip evacuation, reduces heat buildup, and improves surface finish quality. Its overall length of 2‑1/16 inches (52 mm) provides ample reach while maintaining a compact profile suitable for tight workspaces. The product dimensions of 3 × 1 × 1 inches and a lightweight of 6.08 oz make it easy to handle and store, fitting comfortably in standard toolboxes and CNC tool magazines. The KY650 model number reflects Moon Cutter’s commitment to consistent quality and performance across its product line.

Usage

This cutter excels in both CNC and manual milling environments. In CNC routers, the KY650 delivers precise keyseat cuts for gear manufacturing, allowing for tight tolerances and repeatable results across large production runs. Its high speed steel composition tolerates high spindle speeds, making it ideal for rapid machining cycles without sacrificing accuracy. For manual mills, the cutter’s 1/2 inch shank fits standard collet chucks, providing a secure grip and easy tool changes. Woodworkers appreciate the smooth finish on hardwoods, while metal fabricators benefit from the cutter’s ability to produce clean keyseat slots in aluminum and brass. The ten‑flute geometry reduces vibration, which is especially valuable when cutting delicate components or when operating at lower feed rates. The cutter is also suitable for prototyping applications, where quick iteration and reliable performance are essential. Whether you are producing a single custom part or a batch of identical components, the KY650 offers the flexibility and durability required for consistent results.

FAQ

What materials can the KY650 cut effectively?

The cutter is optimized for hardwoods, softwoods, plywood, MDF, and non‑ferrous metals such as aluminum and brass. Its high speed steel material allows it to maintain cutting performance across these varied substrates.

Can I use the KY650 in a standard 1/2 inch collet chuck?

Yes, the 1/2 inch shank is designed to fit standard collet chucks and tool holders, making it compatible with most CNC routers and manual milling machines without the need for adapters.

How many flutes does the cutter have and why does it matter?

The KY650 features ten flutes. More flutes increase the cutting edge contact area, which improves rigidity and reduces vibration, while also allowing for efficient chip removal during high‑speed operations.

What is the recommended spindle speed for this cutter?

For wood applications, a spindle speed of 12,000–18,000 RPM is typical. For metal, especially aluminum, speeds of 8,000–12,000 RPM work well. Always refer to your machine’s guidelines and adjust feed rates accordingly.

Is there a warranty or support if the cutter becomes damaged?

Moon Cutter provides a limited one‑year warranty covering manufacturing defects. Our support team is available to assist with troubleshooting, replacement parts, and any technical questions you may have.
