Sunnen M27 DM45 Diamond Hone Honing Stones Set 4 pcs 150 Grit

Description

Product Overview

The Sunnen M27 DM45 Diamond Hone set is engineered for professionals who demand exacting precision and durability in metal finishing operations. Comprising four individual honing stones, each calibrated to a 150 grit level, the set delivers a balanced blend of material removal speed and surface finish quality. The stones are fabricated from a high‑density diamond‑bonded matrix, providing exceptional wear resistance and consistent performance even under heavy load conditions. Dimensions of each bar measure 4 x 2 x 2 inches, offering a compact footprint that fits comfortably in standard tool holders while still providing ample contact area for efficient honing. The diamond particles are uniformly distributed throughout the bond, ensuring that every pass produces a uniform surface texture without the risk of uneven wear or glazing. This set is compatible with a range of Sunnen model numbers, including AN112, AN600, AN815, ANR275, GNH1010, GNH3610, GNR1010, and GNR3610, making it a versatile addition to any workshop inventory. Designed for both routine maintenance and high‑precision reconditioning, the M27 DM45 series stands out for its ability to extend tool life, reduce cycle times, and maintain tight tolerances across a variety of industrial applications.

Usage

These honing stones excel in environments where consistent surface finish and dimensional stability are critical. Ideal for aerospace component refurbishment, automotive part machining, and general industrial tooling, the M27 DM45 set can be employed on hardened steels, stainless alloys, and even exotic materials such as titanium and nickel‑based superalloys. The 150 grit rating strikes a sweet spot for intermediate honing, removing minor imperfections left by coarse grinding while preparing the workpiece for finer polishing stages. Users typically mount the bars in a standard honing machine or hand‑hold them with a compatible holder for manual applications. The stones’ robust construction tolerates high spindle speeds and sustained pressure, allowing for continuous operation in production lines or batch processing scenarios. Whether you are restoring cutting tools, preparing bearing surfaces, or fine‑tuning gear teeth, the Sunnen M27 DM45 provides reliable performance that translates into reduced rework, lower scrap rates, and improved overall equipment effectiveness.

FAQ

What types of materials can the M27 DM45 stones be used on?

The stones are suitable for a broad spectrum of metals, including hardened carbon steel, stainless steel, titanium, and nickel‑based superalloys. Their diamond‑bonded construction allows them to handle both soft and hard workpieces without excessive wear.

How often should the honing stones be replaced?

Replacement intervals depend on usage intensity and material hardness. For typical industrial applications, users can expect several hundred hours of effective service before noticeable grit degradation occurs. Regular inspection for glazing or loss of cutting efficiency will help determine the optimal replacement schedule.

Can the stones be used in a hand‑held honing setup?

Yes, the 4×2×2 inch bars are designed to fit standard hand‑held holders, making them suitable for manual honing tasks where precise control and flexibility are required. Ensure the holder provides secure clamping to avoid slippage during operation.

Is there a recommended spindle speed for optimal performance?

Sunnen recommends operating the stones at spindle speeds between 2,500 and 4,500 RPM, depending on the material being processed. Higher speeds can increase material removal rates but may generate additional heat, so monitor temperature and adjust accordingly.

What warranty does Sunnen provide for this honing set?

The M27 DM45 set comes with a one‑year limited warranty covering manufacturing defects and premature wear under normal operating conditions. Contact Sunnen customer service with your purchase details for assistance and claim processing.
