Overview

This document is a technical catalog for precision end mills manufactured in Japan, specifically the RSE230, RSES230, and RSB230 series. It provides detailed specifications, ordering instructions, and pricing for various sizes and types of square and ball end mills made from micro grain carbide.

Product Series and Types

• RSE230 Series: Square end mills available in two types:
  Type I - Full cutting length
  Type II - Long neck type
• RSES230 Series: Short flute square end mills with expanded size range, also available in Type I and Type II.
• RSB230 Series: Ball end mills with two types:
  Type I - Full cutting length
  Type II - Long neck type

Specifications

All end mills have the following common features:

• Number of flutes: 2
• Helix angle: 30°
• Material: Micro grain carbide

Dimensions and parameters are provided in millimeters (mm) and prices in Japanese Yen (JPY).

Key Dimensions

• Diameter (D or R for ball radius)
• Cutting length (ℓ)
• Effective length (ℓ1) (optional, mainly for long neck types)
• Neck diameter (d2) and neck taper angle (γ°) for long neck types
• Shank diameter (d) - selectable, typically 3mm, 4mm, or 6mm depending on diameter
• Overall length (L)

Ordering Instructions

When ordering, specify the product code followed by dimensions in the format:

• For RSE230 and RSES230: RSE230 (D) × (ℓ) × [× (ℓ1)]
• For RSB230: RSB230 (R) × (ℓ) × [× (ℓ1)]

Shank diameter must be chosen for diameters 3mm and 4mm. The neck taper angle (γ°) is provided as a reference value.

Product Range and Sizes

The catalog lists extensive size variations for each series, including diameters from 0.1mm up to 80mm or more, with corresponding cutting lengths and effective lengths. Both standard and semi-standard (marked with an asterisk) sizes are available. Semi-standard items require inquiry for price and delivery.

Additional new sizes have been introduced, expanding the RSE230 series to 59 sizes and the RSES230 short flute series to 155 sizes. Options include 5D and 10D cutting lengths, extra-long necks, and same-diameter neck types. These tools are suitable for machining nonferrous materials such as aluminum and copper.

Pricing

Prices vary by size and type, ranging approximately from 3,200 JPY for small diameter short flute tools to over 17,000 JPY for large ball end mills with long necks. Pricing details are provided in tabular form for each product code and size.

Material and Quality

All tools are made from micro grain carbide, ensuring high precision and durability for machining applications.

Additional Notes

• Some sizes marked with an asterisk (*) are stocked by specific trading companies and require direct inquiry.
• The document includes detailed dimensional tables for each product series, specifying all critical parameters for selection.
• The tools are designed for high precision machining, including applications on resin and nonferrous metals.

Summary

This catalog provides comprehensive technical data and ordering guidelines for a wide range of micro grain carbide end mills, including square and ball types with options for full length and long neck designs. It supports precise selection based on machining needs, material compatibility, and size requirements, with clear pricing and availability notes.
