Iscar 3311608 Replaceable Drill Tip 0.295in 134deg IC908

Product Description

The ISCAR 3311608 is a replaceable drill tip designed for use in HCP-IQ series modular drilling systems. It features a 0.295 inch (8.00 mm) cutting diameter with a 134-degree self-centering point angle and a TiAlN coating applied via PVD process. The tip is manufactured from solid carbide at submicron grain material grade IC908, providing strong wear resistance and heat tolerance during interrupted and continuous cuts. It accepts a size 7 insert seat and is held in place by a clamp-style interface. This tip is intended for use by machinists and toolroom professionals working with CNC drilling applications.

The 3311608 is suited for hole making, chamfering, and drilling operations in steel and cast iron as primary workpiece materials, designated under ISO material codes P and K. Secondary workpiece material compatibility includes stainless steel, superalloys, titanium, and hard materials (ISO codes M, S, and H). The helical flute geometry and web-thinned point design support efficient chip evacuation in these demanding materials. It is a fit for production environments where modular drill tip replacement is preferred over full tool replacement.

Key Features

• Solid carbide construction at IC908 submicron grade for extended tool life in ferrous and hard materials
• TiAlN coating via PVD process improves heat resistance and surface hardness
• 134-degree self-centering point angle reduces the need for a center drill or spot drill
• Web-thinned geometry promotes lower thrust force and cleaner entry
• 2-flute helical design supports chip flow in through and blind hole applications
• Clamp-style retention at size 7 seat ensures secure tip seating under load

Compatibility

Designed for use with ISCAR HCP-IQ series modular drill bodies requiring an insert seat size 7. ISO number reference HCP 075-IQ. Conforms to ISO 13399 cutting tool data standards.

Installation Notes

Installation of replaceable drill tips should be performed by a qualified machinist with the spindle locked and machine power isolated. Seat surfaces on both the tip and the drill body should be clean and free of chips or debris before seating the tip. Use the appropriate ISCAR torque key or clamp tool as specified for the HCP-IQ body to avoid under- or over-clamping the insert. Inspect the seat and clamping mechanism for wear at each tip change.
