10pcs TCMT21.51 + 20pcs CCMT09T304/32.51 Carbide Turning Inserts for Lathe Tool Holders

This bundled set combines **10pcs TCMT21.51 (compatible with TCMT110204) carbide turning inserts** and **20pcs CCMT09T304/CCMT32.51 carbide turning inserts**, totaling 30 high-performance inserts for lathe machining. Crafted from durable carbide, the TCMT21.51 inserts ensure stable cutting and wear resistance, perfectly matching 3/8" turning holders and boring bars. The CCMT inserts feature multilayer coating, enhancing heat resistance and extending tool life—ideal as CNC lathe replacement cutters. Both types are designed for seamless use with lathe turning tool holders and boring bars, covering diverse turning needs (from standard to precision machining) on compatible metal workpieces. This all-in-one bundle offers sufficient quantity and versatile specs, suitable for professional workshops and industrial CNC lathe operations.

• Premium Material & Durability Both insert types feature solid carbide construction—TCMT with tin coating, CCMT with multilayer coating. This ensures excellent wear resistance, low friction during cutting, and long tool life. TCMT holders are made of high - quality 40CrMo steel (black oxide finish), adding durability, corrosion resistance, and shock resistance for stable external turning.
• Precise & Diverse Specifications TCMT21.51 (TCMT110204)：Triangle shape (0.093" thick, 0.433" length, 0.25" diameter), ideal for aluminum, steel, stainless steel. CCMT09T304/CCMT32.51：80° indexable, 5/32" thick, 1/64" radius (single - sided), suited for stainless steel, steel, cast iron, non - ferrous metals. Covers varied machining needs for different workpiece materials.
• Superior Cutting Performance TCMT inserts offer wear/heat resistance, avoiding sticking to holders/workpieces during turning. CCMT’s multilayer coating and design ensure fast cutting speed, smooth chip evacuation, and precise finishes. Both deliver stable, efficient cutting on hard metals like stainless steel and alloy steel.
• Broad Industrial Applications Designed for diverse industrial uses—TCMT for turning/finishing stainless iron parts (compatible with S08K/S10K - STFCR11 holders), CCMT for a wide range of materials (stainless steel to non - ferrous). Perfect for workshops and large - scale manufacturing, meeting both standard and precision machining demands.
• Complete Package Value TCMT bundle：10pcs inserts + 3pcs 40CrMo holders + install tools (T8 wrenches, M2.5*8 screws). CCMT bundle：20pcs inserts in a plastic storage box. All - in - one sets provide everything needed for immediate machining, saving time on sourcing separate components.
