827 EDGE FINDERS .375”, .500” AND 10MM BODY DIAMETERS FOR FAST, ACCURATE WORK LOCATION
Work surfaces may be located easily, quickly and accurately with these edge finders. Work with flat, straight edges, shoulders, grooves, round work, studs, dowels or centre points and scribed lines - all can be accurately located with this handy tool. Body and contacts are made of tool steel, hardened, ground and lapped to close tolerances for diameter and concentricity. HOW TO USE: 827MA single end
Edge finders are easy to use. They are placed in a collet or chuck. The worktable is then traversed to obtain contact between the rotating edge finder and the work. Contact will shift to concentric position relative to the body and with very slight additional table adjustment, will move off centre with a decided wobble. At this point, the centre of the finder is exactly one-half the diameter of the contact from the work edge, permitting accurate location for other machining operations relative to the edge. For locating centre points and scribed lines, the pointed contact is used by putting a pencil or rule against the centre point and making it run concentrically. Then the point is brought down to the centre point or intersection of scribed lines and the table is adjusted so that when the tool barely touches the work, the lineup with the point in question can be ascertained. 827 Edge Finders** Item Number Global Item Number Body Diameter Contact Diameter Description Status* Country of Origin DN974 827A .375” .200” Single End MTS CN DN979 827B .500” .200” and pointed contact Double End MTS CN DN984 827MA 10mm 6mm Single End MTS CN DN985 827MB 10mm 6mm and pointed contact Double End MTS CN *MTO Made to order - Products subject to longer lead times when stock is not available.

828 WIGGLER OR CENTRE FINDER WITH ATTACHMENTS Wiggler/Centre Finder S828 and four different attachments adapt to countless applications and are readily interchangeable. The attachments are snapped in the chuck without removing the collet nut and are clamped by a ball swivel-joint that permits adjustment to an angular position or true concentricity. With Pointed Shank 828A, working centres can be quickly and accurately located. Spring tension on the ball of the point permits guiding the point to true concentricity so that the work can be brought into perfect alignment with the machine spindle. Ball Contact 828B is useful in locating work by first bringing the contact (ball diameter .250” or 6.35mm) against the work, a slot, hole, shoulder, or end, and indexing the work to the desired position relative to the spindle. Disc Contact 828C, which has a small disc at the end (.100”/2.54mm) diameter, permits use in more confined areas such as slots or shallow holes.
