Building on its global success machining hardened steels withSumiboron inserts the addition of heat and wear resistant coatingsto a variety of tough new CBN substrates has resulted in a newgeneration of high performance inserts. With economy in mind thenew inserts are multi cornered.
Choose the coated insert suitable for your application and takeyour hard part machining operations to the new industry standard.

Multi Cornered One-Use Type Inserts
One-Use Wiper Insert
Break Master SV Type
CharacteristicsOne-use type inserts improve machining efficiency by using each cuttingedge to its full potential following the numbering system on each cuttingedge then throwing the insert away.
Multi cornered inserts have a single piece of Sumiboron mounted on everyuseable corner. Single sided inserts use the top corners whilst double sidedinserts use both top and bottom corners. Diamond shaped inserts have 4corners and triangular inserts have 6 corners.
A variety of Sumiboron coated grades readily replace expensive grindingoperations for high precision tolerances outstanding surface finish, heavyinterrupted cutting and efficient cost effective machining of hardened parts.

Coated SUMIBORON
BNC100Coated Sumiboron premium grade
for high speed machining of hardened steels
Our copper coloured Sumiboron grade BNC 100 resists prematu-re plastic deformation of the cutting edge by withstanding the hightemperatures that occur when machining hardened steels. Thisnew grade features a heat resistant CBN substrate and a specialTiCN base ceramic coating to enhance surface finish across abroad range of finishing applications at elevated cutting speeds.
Ideal for higher speed machining and suitable for continuous orlight interrupted cuts BNC100 delivers reliable performance andexcellent tool life
General
Advantages High speed machining!Suitable for continuous to light interrupted high speed cutting with vc= 150 ~ 300 m/min.
Extended tool life!Wear resistant ceramic coating and tough CBN substrate considerably extends tool life.
Excellent surface finish!A consistent surface finish to values less than 6.3Rz is easily achieved on both continuousand light interrupted cut applications.

BNC160High precision machining with surface finishes
down to 1,6 Rz possible thanks to smooth coating!
Use the copper coloured Sumiboron grade BNC160 to impro-ve surface integrity as well as machining accuracy.The TiCN-base smooth surface ceramic coating and thenewly developed Sumiboron substrate enhances edgestrength and wear resistance making high precision machiningwith surface finishes as low as 1,6Rz readily achievable.
This new grade is ideal for turning components that previouslyrelied on precision grinding machines for final machining.
General
Advantages Excellent surface roughness!A consistent surface roughness is maintained for hours because wear at the boundary is so gradual.
High Precision MachiningHigh precision work previously ground, can now be turned.
Enlarged scope of application!A wider range of hardened steels can be cut using Sumiboron the result being high productivityon close tolerance machining applications.

General
Heavy Interrupted CuttingContinuous Cutting
Use our gold coloured Sumiboron grade BNC300 to machinehardened steel parts which have heavy interruptions.
The tough new CBN substrate in combination with the toughwear resistant coating responds well to applications wherecuts over surfaces which are heavily interrupted by grooves,cross holes, etc have to be undertaken.
Performance
Advantages Stable tool life!Tough CBN substrate and wear resistant coating provides stable tool life even when cutsare heavily interrupted.
Excellent machining accuracy!The wear resistant coating protects the cutting edge from surface damage maintaininginsert shape - sizing accuracy and excellent surface roughness.
Expanded application range!BNC 300 extends tool life across a broad application range from continuousto heavy interrupted cutting.
