Iscar 5509472 Replaceable Drill Tip 0.311 in IC908 Tialn

Product Description

The ISCAR 5509472 is a replaceable drill tip designed for indexable drilling systems in the ICM series. It features a 0.311-inch (8.00 mm) cutting diameter with a 140-degree point angle and a standard point type with web thinning for improved chip evacuation. The tip is manufactured from solid carbide using a submicron material grade and is PVD-coated with TiAlN for heat and wear resistance. Seat size 7 allows direct installation into compatible ICM-series drill bodies. This tip is used by machinists and tool-room professionals performing precision hole-making operations in demanding materials.

The ISCAR 5509472 is suited for drilling stainless steel, superalloys, and titanium as its primary application materials, with secondary capability in steel, cast iron, and hard materials. The 2-flute helical flute design with regular spiral promotes consistent chip flow in these tough workpieces. With a functional length of 0.1351 inches and an overall length of 0.1812 inches, this tip fits compact tooling setups in both CNC machining centers and manual drilling applications where short, rigid cutting tools are required.

Key Features

• 0.311-inch (8.00 mm) cutting diameter with 140-degree included point angle
• Solid carbide construction, submicron material grade for edge toughness
• TiAlN coating applied via PVD process for thermal and abrasion resistance
• Web-thinned geometry for reduced thrust force at entry
• 2-flute helical design with regular spiral for controlled chip removal
• Insert geometry M, seat size 7, clamp-held in ICM-series drill body

Compatibility

Designed as a replaceable tip for ICM-series indexable drill bodies requiring seat size 7. ISO number reference: ICM 079. Compatible with ICM-series drill holders accepting this seat size and geometry as specified by the manufacturer.

Installation Notes

Installation of replaceable drill tips should be performed by a qualified machinist or tooling technician. Ensure the drill body is fully secured and the machine spindle is locked or the machine is powered off before seating or removing the tip. The tip is clamp-held; use the appropriate torx or hex key specified for the ICM-series clamping mechanism and avoid over-torquing the clamp screw. Inspect the seat for chips or contamination before installation to ensure proper tip seating and runout performance.
