The part (workpiece) to be held forms the closing of the magnetic loop or path, onto those fixed plates, providing a secure anchor for the workpiece. Soft jaws are made of soft materials such as soft (unhardened) metal, plastic, or wood. Many chucks have jaws, (sometimes called dogs) that are arranged in a radially symmetrical pattern like the points of a star. A spider is a simple, relatively inexpensive, limited-capability version of an independent-jaw chuck. Keyless designs offer the convenience of quicker and easier chucking and unchucking, but have a lower gripping force to hold the tool or workpiece, which is potentially more of a problem with cylindrical than hexagonal shanks. 95 In Stock Drill Chuck Arbor - MT2/JT6 (G1434) 6 $ 12. One of the more popular brands is Jacobs, and most manufacturers will list an equivalent number, which can make determining a replacement key a bit easier.

The name SDS comes from the German steck, dreh, sitzt (insert, twist, fits). The chuck is held in place with bolts through clearance holes that do not affect the alignment which is entirely provided by the register. One of the corollaries of the conical action is that collets may draw the work axially a slight amount as they close. Contact Seller Ask for best deal. These chucks are best suited to grip circular or hexagonal cross-sections when very fast, reasonably accurate (±0.005 inch [0.125 mm] TIR) centering is desired. [9] By 1807 the word had changed to the more familiar 'chuck: "On the end of the spindle … is screwed … a unversal Chuck for holding any kind of work". Some are equipped with a locking mechanism for hammer drilling and also screwdriver operations (clockwise and counterclockwise). [15] His son-in-law Austin F. Cushman (1830–1914) developed the ideas and sold chucks through his business, Cushman Industries.[16]. Drill with incrementally increasing diameter steps. The collet can be squeezed against a matching taper such that its inner surface contracts to a slightly smaller diameter, squeezing the tool or workpiece whose secure holding is desired. Maximum drill size (diameter) that can be used. Pin chucks are also used with high-speed rotary tools other than drills, such as die grinders and jig grinders. (The axial movement of cones is not mandatory, however; a split bushing squeezed radially with a linear force—e.g., set screw, solenoid, spring clamp, pneumatic or hydraulic cylinder—achieves the same principle without the cones; but concentricity can only be had to the extent that the bushing's diameters are perfect for the particular object being held. Size : 6.5 mm, 10 mm, 13 mm, 16 mm : Model Name/Number : JT 6 : Usage/Application : Used to hold an object with radial symmetry, especially a cylinder. Find Local Shop Online. Thank you For Visiting.

Some high-precision chucks use ball thrust bearings to reduce friction in the closing mechanism and maximize drilling torque. Find Local Shop Online. Electrostatic chucks may have pins, or mesas, the height of which is included in the reported dielectric thickness; a design by Sandia National Laboratory uses a patterned silicon-dioxide dielectric to form the pins. Large drill bits can have straight shanks narrower than the drill diameter so that they can be fitted in chucks not able to chuck the full diameter. Indeed, hot-rolled or other imperfectly round workpieces may "teeter" insecurely between opposing jaws of scroll chucks having even numbers of jaws, in the same manner that a four-legged stool teeters on a rough floor while a three-legged stool never does. As auxiliary features that complement the main lathe chuck: To hold the bar or workpiece at the back end of the spindle bore and support it concentrically, so that it resists wobbling or whipping while the spindle is turning. Three-jaw chucks are often used on lathes and indexing heads.

The Jacobs Taper (JT) is commonly used to secure a drill chuck to an arbor. Thread Mounted Drill Chucks, with key. Collets usually are made to hold cylindrical work, but are available to hold square, hexagonal or octagonal workpieces. By having twice as many clamping points, a six-jaw chuck induces less than half as much clamping distortion in a thin-walled workpiece, compared to a three-jawed chuck. Range of spindle speeds and range of feeds. SDS relies on a tool having the same shank diameter as the chuck; there are three standard sizes: Many SDS drills have a "rotation off" setting, which allows the drill to be used for chiselling. The drill is inserted into the pin chuck and tightened; the pin chuck has a shaft which is then inserted into the larger drill chuck to hold the drill securely. The original forms of workholding on lathes were between-centers holding and ad hoc fastenings to the headstock spindle. These pole pieces are usually flush with the housing surface. The penalty is that most collets can only accommodate a single size of workpiece. Although this idea is conceptually interesting, the simpler chucking systems mentioned in the previous paragraph are probably a marketplace winner over this alternative for most applications, because they supply the same capabilities via a simpler, less expensive solution. There are hybrid self-centering chucks that have adjustment screws that can be used to further improve the concentricity after the workpiece has been gripped by the scroll jaws. Industry-standard spindle nose designs allow wide. Draw-in is not always a problem, but avoiding it can be helpful on some work where failing to account for it might result in inaccuracy on part overall length, shoulder lengths, etc. All Albrecht Precision Drill Chucks, except for the Key-Lock models, incorporate a unique self-tightening feature that causes them to grip drills tighter as more torque is applied.
