Whilethe single-flute countersink is slow cutting, it will work well in a non-rigid machining setup. Four flutes provide more chipclearance than six do. This is a consideration in machining stringy materials such as some plastics and nonferrous factors being equal, the six-flute countersink will give more service life than the four-flute tool because the cutting loadis distributed over more DesignResonant vibration is the cause of chatter in rotating cutting tools. Every tool/machine/workpiece system has naturalfrequencies at which such vibration will occur.
2 Severance Countersinks are designed with staggered cutting edges, whichinhibit the occurrence of resonant, or harmonic vibration. Tools with symmetrical cutting edges tend to multiply thefrequencies at which chatter occurs, and to reinforce the vibration. Chatterless design can t change the natural frequencies ofthe system, but it takes tool geometry out of the Countersinks for Special JobsWhat makes the Severance line unique is the number of proprietary and special tools we can supply to fit some specificapplications. 3N1 Drill Points (see page 57 - 59) offer some cost-cutting opportunities to the creative tool engineer. CNC-K Precision Countersinks (pages 53 - 54) are used in numerical control and other preset tooling systems. Such applications exist in almost any modern production machining facility.
3 Stop Countersink Systems (pages 64-67) are in wide use in the aircraft industry, where they are used with hand-held power tools to countersink rivet holes. Special Tools which combine Countersinks with drills, steps, pilots, radii and other custom shapes are readily available from Severance . Just send in a sketch or description for CountersinksVery few tool rooms or sharpening servicesare equipped to recondition worn chatterless Countersinks . Our regrinding service is fast,competent and economical. Whenever yousell chatterless cutters, be sure to recommendSeverance Countersink For Every UseSeverance Tool Industries, Inc. manufactures countersinkswith one, four and six flutes, carbide and high speed steel, Countersinks with pilots and drill points, heavy-duty toolsand specials. Sizes range from 1/8" to 3", and almost anycenterline angle can be specified.
4 These standard tools willhandle at least 99% of all countersinking applications ..and we can build specials to satisfy any other or Steel?When machining hard or abrasive materials, carbidecountersinks will often give 10 or more times the service lifeof high speed steel tools. As a rule of thumb, considercarbide for production operations with cast iron, alloy steelor glass-reinforced plastics. High speed steel is generallymore economical in low carbon steel and nonferrousmachining applications. In automated productionoperations, the cost of changing a tool can exceed the cost ofthe tool.

Our tools feature a positive shearing action, are designed to takeheavy cuts and produce exceptionally smooth seats. These six fluted Countersinks givelong service life because the cutting load is distributed over six cutting them in your milling machine, drill press, screw machine, lathes, automatics,special machines, feed units, and hand tools. See also page 53-54 for our CNC-K Chatterless- Countersinks for CNC lathes and Machining Centers.
