Seco 17013182 Corner Chamfer End Mill 1in 4 Flute Cobalt

Product Description

The SECO 17013182 is a corner chamfer end mill engineered for demanding material removal in stainless steel, superalloys, and titanium. Built from M42 cobalt high-speed steel, it features a 1-inch cutting diameter, a 4-inch length of cut, and four helical flutes with a super-close pitch for stable, chatter-resistant performance. The 45-degree chamfer at 0.0300 inches wide handles edge-breaking and chamfering in a single pass. With a 6.5-inch overall length and a 1-inch Weldon flat shank, this tool is sized for rigid setups in vertical and horizontal machining centers. Machinists working exotic alloys and high-strength materials will recognize this as a workhorse roughing tool for slotting, shouldering, ramp-down, and helical interpolation operations.

The 17013182 belongs to the SECO VFP635 series (catalog number VFP435-1.000-D4-C030.3-Z4), which targets long-reach roughing and finishing in difficult-to-machine materials. Its centercutting geometry supports plunging and recessing operations directly into the workpiece without a pre-drilled pilot hole. The single-end configuration and right-hand flute direction suit standard CNC milling setups. This tool is appropriate for job shops, aerospace component machining, and industrial manufacturing environments where stainless steel, nickel-based superalloys, and titanium are common workpiece materials.

Key Features

• M42 cobalt construction for heat and wear resistance in high-alloy workpiece materials
• 4-flute helical design with super-close pitch reduces vibration during roughing passes
• 45-degree chamfer at 0.0300 inches wide for one-step edge chamfering and blending
• Centercutting geometry enables direct plunging, recessing, and drill-mill operations
• Weldon flat shank provides positive drive and minimizes pullout risk under heavy cuts
• Supports shouldering, slotting, ramp-down, and helical interpolation in a single tool
• Bright/uncoated finish — no coating delamination risk; re-sharpen without coating loss

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for CNC machining centers accepting a 1-inch straight shank with Weldon flat. Primary workpiece materials are stainless steel, superalloys, and titanium (ISO material groups M and S).

Installation Notes

Installation requires a collet chuck, end mill holder, or Weldon-style side-lock holder rated for a 1-inch shank diameter. Verify holder runout before seating the tool, as runout amplified over a 4-inch reach can accelerate edge wear on difficult materials. Always spin the spindle in the correct right-hand cutting direction and confirm workholding is rigid before engaging a full-depth roughing pass. Follow your machine tool manufacturer and shop safety guidelines for speeds, feeds, and coolant strategy when cutting titanium or superalloys.
