VAPOR™ VAPOR™ is created for lighter, faster cutting, ideal for new machine tool technology. • A new double-sided series for lower cost per usable cutting edge • Designed with a positive cutting edge and excellent ramping capability • Large insert screw for longevity and easy indexing Shell Mills VAPOR™ End Mills are available in six cutting diameters for just the right tool, ranging from .5” to 1.5” and from 1 to 6 utes. The overall length ranges from just under 4” to almost 8”, providing stable longreach cutting. VAPOR™ Shell Mills are available in 1.5” and 2” diameters with 6 and 7...

Product Selector The VAPOR™ series is a 6-edged high feed insert offering outstanding cost per edge value. A strong cutting edge design provides excellent material removal and stability in roughing applications. Cutter bodies are made from tool steel and heat-treated to optimize longevity and wear resistance. S End Mills VAPOR™ end mills cover a wide variety of lengths and diameters. All feature ne-pitch for fast feed rates and optimum material removal. Dapra recommends using the shortest tool suitable for optimum rigidity. End mills are equipped with through-coolant standard. Program...

Modular Heads VAPOR™ also comes in modular adaptations, offering long-reach capability and the value proposition of replacing a screw-on head vs a solid tool. Use modular heads with Dapra’s carbide core, heavy metal, or solid carbide modular extensions for optimum long-reach roughing. Modular heads are equipped with through-coolant standard. D R Effective Effective Diameter Length Program Radius (Bull Nose) Shell Mills VAPOR™ offers ne-pitch cutters for high material removal rates. Shell mills are equipped with through-coolant standard.

Carbide Core Modular Extensions Ideal for Standard Inch End Mill Holders › All styles of modular extensions are universal – use them with any of our screw-on modular heads, as well as many competitors’ modular heads Cylindrical inch shanks, providing adaptation for end mill holders (add your own at), milling chucks and heat-shrink holders 3 sizes to accommodate modular head sizes from 3/4” to 1-1/2” Carbide core for enhanced vibration dampening capability; reduced deection and improved rigidity Optional add-on extensions for additional 2” reach – screw on to base extensions (for 3/4” to...

Solid Carbide Modular Extensions › Optimum rigidity reduces deection and chatter Best option for nishing with modular heads Thru-coolant for delivery of air or coolant right at the cutting edge Solid Carbide Modular Extensions EDP Effective Length Heavy Metal Modular Extensions › Made of high-density tungsten, providing extra resistance to vibration and deection Machined on both ends; can be cut in half and d used with two different modular heads Metric shank diameter provides clearance for each inch size modular head M (MOUNTING THREAD, (MOUN BOTH ENDS) Thru-coolant equipped Heavy Metal...

Tri-X2 Inserts VAPOR™ insert technology includes a positive cutting edge and extra bottom clearance for a smooth chip ow and excellent ramping capability for a double-sided insert. All edges are labelled with “dots” or “dashes” to aid in indexing accuracy. T Geometry Our inserts use dedicated grades and geometries for most material groups. “T” geometry is for steels, irons and heat-treated steels.

Technical Considerations • Always use anti-seize compound on screws. • Change insert screw every 10 inserts. • Use the shortest-length tool holder (end mill holder) for maximum rigidity; the shank of the cutting tool should be up inside the machine spindle taper whenever possible. • Thoroughly clean pocket and screw at each insert change. • Use tool holders appropriate for roughing operations: end mill holders and power chucks recommended; collets are not recommended.

Actual speeds and feeds will depend on many variables, such as rigidity, workpiece hardness, tool extension, machine accuracy, Depth of Cut, etc. Start at the middle of the SFM range and the low end of the FPT range. Next, increase FPT to optimize productivity and tool life. Higher SFM will provide higher output but may reduce tool...
