TTC PRODUCTION CY38 3/8″, 4″ Long CY Centerless Ground Carbide Round Solid Carbide Drill / Reamer Round Blank Hot Picks

Benefits

Carbide blanks are sintered from tungsten carbide powder and a cobalt binder, producing a substrate that typically runs 8993 HRA with transverse rupture strength in the 350500 kpsi range. Grain structuresubmicron, ultra-fine, or fineand cobalt content (commonly 612%) are matched to balance hardness against fracture toughness for the intended tool family. Tight control over density, binder distribution, and centerless-ground OD tolerances yields a consistent, defect-free substrate ready for flute grinding and coating.

Features

• Substrate-grade carbide: Manufactured from submicron and ultra-fine grain tungsten carbide grades, delivering the hardness, fracture toughness, and edge stability required for high-SFM machining of hardened steels, superalloys, titanium, and abrasive composites.
• Tight dimensional control: Centerless-ground OD tolerances and controlled length, straightness, and concentricity reduce stock removal at the grinder and keep runout in-spec through finish grinding and flute work.
• Multiple geometries and configurations: Available as round (unground and grind-stock), square, radius, strip, split-end, and center-tip blanks to suit end mill, drill, reamer, insert, and form-tool production.
• Coating- and grind-ready surface condition: Consistent surface finish and binder distribution support repeatable flute grinding, edge prep, and downstream PVD/CVD coating adhesion without delamination or pinholing.
• Built for tool builders: Tight lot-to-lot consistency in hardness, grain structure, and density gives regrind houses and OEM tool manufacturers a predictable input, the same blank performs the same way every batch.
