Iscar 5509471 Carbide Replaceable Tip Drill 0.307 in Tialn

Product Description

The ISCAR 5509471 is a solid carbide replaceable tip drill insert in the ICM series, designed for high-precision drilling operations in demanding materials. It carries a TiAlN coating applied via PVD process, which provides thermal resistance and extended tool life in abrasive or heat-generating cuts. The tip measures 0.307 inches in cutting diameter with a 140-degree included angle and a thinned web point geometry. At 0.031 pounds, this insert is a compact, single-use replaceable component that seats into compatible ICM series drill bodies without regrinding. Intended for use by machinists and tool-and-die professionals working in production or job-shop environments.

This replaceable tip drill insert is engineered primarily for stainless steel, superalloys, and titanium (ISO material groups M and S), with secondary suitability for steel, cast iron, and hard materials (ISO groups P, K, and H). The slow spiral flute type and T-Land style geometry are well matched to the controlled chip formation requirements of these workpiece materials. The 140-degree drill point and web-thinned construction reduce entry force and improve centering on difficult-to-machine surfaces. Typical applications include through-hole and blind drilling on CNC machining centers where replaceable-tip tooling is specified for cost-per-hole efficiency.

Key Features

• Solid carbide submicron-grade substrate with IC908 manufacturer grade for wear resistance in tough alloys
• TiAlN PVD coating for high-temperature performance in stainless steel, superalloy, and titanium cuts
• 140-degree included angle with web-thinned, thinned point for reduced thrust and accurate entry
• Slow spiral flute type with T-Land insert geometry optimized for controlled chip evacuation
• 2-flute configuration in ICM series with twist insert holding method for secure seating
• Conforms to ISO 13399 tooling data standards for digital tool management integration

Compatibility

Designed as a replaceable tip insert for compatible ISCAR ICM series drill bodies accepting insert seat size 7, per ISO number ICM 078. Specific drill body compatibility should be confirmed against the ISCAR ICM series tooling catalog before ordering.

Installation Notes

Installation of replaceable tip drill inserts should be performed by a qualified machinist with the machine powered off and spindle locked. The insert seat should be inspected and cleaned before seating the new tip to ensure full contact and accurate runout. Use the correct torque tool as specified by the drill body manufacturer — do not overtighten or use improvised tools. Confirm tip seating and runout with a dial indicator before returning the tool to service.
