Model: SBHA — Milling Cutter Component Key specifications Model number: SBHA Application: Milling cutter Material options: 40CrMo steel or 42CrMo steel Hardness: HRC 58 (heat-treated) Why you need this product Consistent hardness (HRC 58) provides a balance of toughness and wear resistance, reducing edge chipping and prolonging service life under milling loads. Choice of 40CrMo or 42CrMo lets you select the steel grade that matches your shop practice or procurement while keeping the same performance level. Designed specifically for milling cutter use to maintain cutting geometry and minimize downtime from frequent tool changes. How it solves common problems Reduces tool wear and frequency of replacements compared with untreated or lower-hardness components, lowering operating cost. Stable material properties under load help preserve surface finish and dimensional accuracy on machined parts. High hardness and proper material selection limit deformation and increase resistance to abrasive and impact wear. Important attributes Function: Intended for use in milling cutter assemblies to provide a durable cutting/holding component. Compatibility: For use where SBHA model components are specified or where 40CrMo/42CrMo, HRC58 parts are required; suitable for common milling operations. Material & performance: 40CrMo and 42CrMo are chromium-molybdenum steels, heat-treated to HRC 58 to deliver reliable toughness and wear resistance under typical milling conditions. Practical applications / use scenarios Precision face milling of steel components in a job-shop environment where consistent cutter hardness is required to maintain surface finish. Roughing and semi-finishing operations on alloy steel workpieces where durability and resistance to chipping extend effective cutting life. Replacement component for milling cutter systems specified to SBHA model requirements in automotive or heavy machinery part production. Notes Product details are limited to model SBHA, material (40CrMo or 42CrMo), and hardness HRC 58 as specified. Please confirm fit and compatibility with your specific cutter assembly before ordering.
