Product Description
CMT Solid Carbide Straight Bit - Long Series, 5/16 in. Diameter with 1/2 in. Shank is engineered for industrial nesting applications where precise, clean-edged cuts are essential. Built from micrograin carbide with special Fatigue Proof steel construction, this three-flute router bit delivers smooth, accurate straight cuts even under the heaviest continuous workloads. The long-series design provides an extended 1 1/8 in. cutting height, making it well suited for deep dadoes, grooves, and panel routing tasks on CNC machines, router tables, and handheld routers alike.
Key Features
- Solid micrograin carbide construction - provides exceptional hardness and edge retention, so the bit stays sharp through demanding industrial nesting cycles and high-volume production runs.
- Special Fatigue Proof steel body with micrograin carbide cutters - resists mechanical fatigue under heavy loading, reducing the risk of tool failure during long cutting sessions.
- Double-faced, razor-sharp cutters - produce a clean, finished edge on both faces of the workpiece, minimizing tearout and reducing the need for secondary sanding or trimming.
- 3-flute (3-tooth) geometry - balances feed rate and surface finish, allowing faster material removal while still achieving a smooth, precise cut in sheet goods and solid materials.
- Long-series 1 1/8 in. cutting height - enables deeper single-pass cuts compared to standard-length straight bits, improving efficiency in nesting and panel processing applications.
- 1/2 in. shank diameter - provides a secure, stable connection in standard 1/2 in. collets, reducing vibration and improving cut accuracy at the tool.
- Right-hand rotation - compatible with conventional router spindle direction for straightforward installation and consistent performance on CNC routers and handheld routing equipment.
Why This Product
- Designed specifically for industrial nesting applications, this long-series solid carbide bit handles the repetitive, high-demand cutting cycles common in cabinet, furniture, and panel production environments without sacrificing cut quality.
- The razor-sharp, double-faced micrograin carbide cutters deliver a beautiful clean edge on finished pieces - reducing rework time and improving the quality of the final product straight off the CNC or router table.
- The extended 3 in. total length and 1 1/8 in. cutting height give operators the reach needed for deep straight cuts and full-thickness panel routing in a single pass, improving throughput in production settings.
- The 1/2 in. shank combined with solid carbide construction provides the rigidity and vibration resistance needed for accurate, repeatable cuts in MDF, plywood, laminates, melamine, and other demanding sheet materials.

Frequently Asked Questions
What makes this bit suitable for industrial nesting applications?
This bit is built from special Fatigue Proof steel combined with micrograin carbide cutters that can withstand even the heaviest workloads. The three-flute, long-series design delivers a smooth, precise cut and a clean finished edge on every pass - making it reliable for the repetitive high-cycle cutting that industrial nesting on CNC machines demands.
What is the difference between this long-series bit and a standard-length straight bit?
The long-series designation refers to the extended cutting height of 1 1/8 in. and a total length of 3 in. - both longer than typical standard-series straight bits. This added reach allows for deeper cuts in a single pass through thicker panel materials, which is particularly valuable in nesting and cabinet production workflows.
Is this bit compatible with a 1/2 in. router collet?
Yes. This bit features a 1/2 in. shank, designed to fit any router or CNC spindle equipped with a standard 1/2 in. collet. It is compatible with handheld routers, router tables, and CNC routing machines that accept this collet size.
What materials can this solid carbide straight bit cut cleanly?
The double-faced, razor-sharp micrograin carbide cutters are well suited for routing solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic. The three-flute geometry helps achieve a clean edge on both faces of the workpiece across all of these materials.
