GRADES FOR HOLEMAKING The ingenious solution that takes cutting tool materials to another level Features • Improved adhesion and insert chipping resistance • Stable and extended tool life in continuous and interrupted cutting operations • Reduced cutting friction and minimized built-up edge on exotic materials • High quality surface finish on the work pieces

GOLD RUSH GRADES FOR HOLEMAKING APPLICATIONS IN1030 (PVD) CAST IRON, STAINLESS, TITANIUM Great for tough, slower speed applications. A good option when machine rigidity is an issue. IN2505 (PVD) GENERAL PURPOSE An improvement over the current IN2005 grade, IN2505 has a multi-layered PVD coating for a wide variety of materials. IN6505 (CVD) STEEL APPLICATIONS A 10μm thick layer has been added to the CVD coating that enhances toughness and wear resistance. It makes this grade suitable for high speed steel machining. 257

REPLACEABLE TIP DRILLS Ingersoll Cutting Tool Company is proud to announce the expansion of : The Next Generation of Replaceable Tip Drills. This new design is a standard product line with tip diameters ranging from .2756” – 1.0197” (7mm ~ 25.9mm) in 0.004” (.1mm) increments and drill bodies available in 1.5xD, 3xD, 5xD and 8xD length to diameter ratios. The precision bodies have an improved pocket design and innovative clamping system that provide stable performance after multiple tip indexes. These drill bodies also feature twisted coolant holes, polished flutes, and a PVD-coating that...

DRILL BODY COMPARISON: GOLD TWIST VS. QWIK TWIST The new Gold Twist pocket design's contact/clamping area is three times deeper than our current Qwik Twist drill. The accuracy of the added cylinder to the clamping area improves rigidity and helps reduce internal stresses. The two precision ground positive stop locations improve the drilling tips' position and support.

Prior to using 8xD or 12xD drills, it is recommended to drill pilot holes from 0.5xD~1.5xD using a short drill ( 1.5xD holder is recommended). 2. Approach the pre-hole at reduced speed and feed until 2~5mm from it’s bottom depth. 3. Increase up to recommended speed and maintain feed rate for 2~3 seconds applying coolant. 4. Start drilling at the recommended feed rate.
