EHWA DIAMOND – since 1975

Connect material, cutting edge and machining task

This catalogue combines the complete technical content of twelve short EHWA product documents. D-BITE precision tools, PCD, PCBN, carbide and coatings remain distinct tool or material concepts. Series and article designations and technical differences between individual applications are retained.

The tables reproduce the programmes in their respective sources. Historical lists labelled “Stock” serve as product and specification references here; current stock and a suitable design are discussed with EHWA Europe. Test results remain directly associated with their cutting conditions.

Editorial edition: 13 October 2026. This date identifies the new editorial version rather than redating every underlying HQ document.

Industry images from the solid carbide drill product sheet

The solid carbide drill cover shows vehicle manufacturing and strip and tubular products as industry images. These photographs provide industrial context. Suitability for a particular material is defined by the respective tool programme; the images do not extend the steel application described for ET220.

ET110 is described as a fine carbide material with a polished surface for highly polished drills. The polished tool surface is intended to prevent built-up edge formation and support smooth chip flow. The source identifies “Mirror Finish Lower than Rz 0.4”. Rz < 0.4 remains associated with the illustrated tool surface; no unit is printed there. It is not presented as a guaranteed roughness of the resulting hole.

Standard coatings: properties and application ranges

The coating document distinguishes eight grade designations. The following table contains every colour, hardness value, temperature value and feature. HV and °C are established by the supplementary EHWA Coating Service table; all numbers remain the values in the coating document reproduced here.

Grade Colour Hardness (HV) Maximum temperature (°C) Features described by EHWA
TN Gold 2300 600 Single-layer coating; typically used for wear parts; used insert edges easy to identify
TA Purple grey 2300 900 Good heat and wear resistance; conventionally used for cutting tools
AC Silver grey 3200 1100 Better heat resistance than TA; high hot hardness and oxidation resistance
AC2 Light grey 3700 1100 High heat resistance; higher hot hardness and oxidation resistance than AC
TNP Dark grey 3600 1100 High wear resistance, good surface finish and heat resistance; described for hardened steel and bearing steel
H1 Copper 3600 1200 Multilayer coating for interrupted cutting; high wear and oxidation resistance
H2 Blue 4000 1200 Multilayer coating for interrupted cutting; high wear and oxidation resistance
H3 Rainbow 3600 1200 Multilayer coating for interrupted cutting; high wear and oxidation resistance

The 1200 value is shared by H1/H2/H3 in the original table. “New” markers for AC2 and H1/H2/H3 describe the source's historical edition; they are not presented as current launches.

EHWA designation Coating name in the application matrix

Coating application matrix for cast iron, hardened steel, powder metal and bearing steel; original range bars retained.

The matrix distinguishes cast iron, hardened steel labelled HRC45~, powder metal labelled HRC45~, and bearing steel. Its bars show different application ranges within and across these columns. The plus signs remain part of the printed coating names; no additional chemical formula is inferred from them. Coating, cutting material and continuous or interrupted cutting are selected together.

EB150: PCBN for valve seat rings

EB150 is developed for valve seat rings in engine cylinder heads. A TiN-based ceramic binder and CBN grains support impact and wear resistance, useful tool life and good surface finish. The grade is designed for hardness variations in sintered alloys; EHWA also identifies applications in high-output engines.

PCBN grade selection: EB428, EB419, EB454, EB210 and EB71X

Grade selection links workpiece material, cutting speed and interruption. For hardened steel above HRC 50, the source shows H05, H15, H25 and H35. The supplementary manufacturer's grade guide defines these as continuous cutting, light, medium and heavy interruption. The second selection chart distinguishes grey cast iron and ductile iron, with finishing and roughing applications.

Grade selection for hardened steel above HRC 50: cutting speed in m/min and interruption from H05 to H35. Original region shapes and grade labels are retained.

Grade Cutting conditions and benefits stated in the source
EB428 Continuous cutting. Good wear resistance at high temperatures; suitable for heat-treated steel and ductile iron at high speed. The TNP coating improves heat resistance.
EB419 Continuous to medium interrupted cutting. Good wear resistance in heat-treated steel; TNP coating provides high heat resistance.
EB454 Light to heavy interrupted cutting. For heat-treated steel at intermediate to high speed; TNP coating supports heat resistance and edge sharpness.
EB210 Heavy interrupted cutting. The source highlights impact and wear resistance for high-speed machining of high-hardness cast iron.
EB71X High-CBN-content grade for cast iron machining.

PCD helical endmills: high feeds and small tool designs

EHWA helical endmills support high-feed machining, high material removal rates and high process reliability. A high rake angle helps to prevent burr formation; the source highlights high speed, efficient machining and good surface finish. The tools combine PCD cutting edges with a tungsten carbide shank. Tool designs and configurations can be adapted to customer requirements.

Solid HBN: cutting material series for cast iron roughing

HBN here identifies EHWA’s cutting material series, a PCBN type produced by a special manufacturing method. The source positions it as offering greater wear resistance and hardness than ceramic, and as a more economical alternative to the compared PCBN designs. It highlights performance in cast iron roughing.

Qualitative positioning of ceramic, Solid HBN and PCBN: hardness/abrasive wear resistance versus fracture toughness/transverse rupture strength. The regions contain no absolute measurements.

Four HBN grades

The table retains all grade names, grit sizes and CBN volume fractions. The graphical property comparisons for mechanical wear, chemical wear and toughness remain relative source comparisons.

Grade Grit size (µm) CBN volume fraction Characteristics
HBN-W 10 85–90 % Standard grade for grey cast iron
HBN-B 20 85–90 % Improved wear resistance
HBN-N 4 90–95 % Improved surface finish
HBN-O 6+12 85–90 % Improved wear resistance and toughness
Original relative property comparison: HBN-W/HBN-B/HBN-N/HBN-O. Block counts and partial block lengths are retained; the source does not state an absolute measurement scale.

Discuss your cutting tool application

Workpiece material and hardness, component drawing, machining operation, tool interface and machine provide the starting point. Existing cutting conditions, interruption, coolant supply and the required surface quality support the choice of grade, cutting geometry and coating. For inserts, start with the model and order code; for custom tools, add the required shape and dimensions.
