Replaceable bushing used for extraresistance to rotational forces under harsh conditions.

4 This bushing,generally used with a liner, has a milled locking flat to allow fasten-ing securely with a flat clamp. FM BUSHINGS also have a standardrecess on the other side to allow using a lockscrew :Types L and PM (metric). Liners are permanent BUSHINGS used tohold renewable DRILL BUSHINGS . The liner s ID has a precise sliding fitwith the renewable bushing s OD. The hardened liner accuratelylocates the renewable bushing and protects the jig plate from wearcaused by frequent bushing replacement. Note: Metric liner bushingsare the same as metric press-fit LINER:Types HL and HM (metric). Similar to an L bushing, but with a head toresist heavy axial loads.

5 Head liners are permanent BUSHINGS used tohold renewable DRILL BUSHINGS . The head liner s ID has a precise slidingfit with the renewable bushing s OD. The hardened head liner accurate-ly locates the renewable bushing and protects the jig plate from wearcaused by frequent bushing replacement. Note: The length listed for ahead liner refers to its overall length, not its length under the head. Metrichead-liner BUSHINGS are the same as metric head-press-fit LINER:Types UL and ULM (metric). Similar to an HL head liner, but incor-porating a special locking tab that eliminates the need for alockscrew. Un-A-Lok liners are permanent BUSHINGS used to holdSF renewable DRILL BUSHINGS (on the slip side only, not the fixed side).

6 Although slightly more expensive than a head liner plus a lockscrew, installation time is dramatically FIT:Types P, PC (carbide), and PM(metric). This is the most-popularand least-expensive DRILL bushing. P BUSHINGS are permanentlypressed into the jig plate, usually flush with the top surface. They aregenerally used for single-step drilling or reaming operations whenyou do not expect to replace BUSHINGS during the tooling s lifetime. Pbushings can be mounted closer together than headed BUSHINGS , butoffer less resistance to heavy axial H, HC(carbide), and HM(metric). Similar to a P bushing, butwith a head to resist heavy axial loads. H BUSHINGS are permanentlypressed into the jig plate.

7 They are generally used for single-stepdrilling or reaming operations when you do not expect to replacebushings during the tooling s lifetime. The head can be left exposed,or recessed by counterboring the installation hole. Note: The length listed for a USA head-press-fit bushing refers to its length under thehead, while the metric version s length is its overall PRESS FIT:SERRATED PRESS FIT:Types SP and SPM (metric). Similar to a P bushing, but with top ser-rations to prevent rotation in soft materials. Recommended in high-torque situations for materials such as magnesium, aluminum,masonite, or wood. Finish-ground OD ensures accurate ID also resist axial force to prevent pushing the bushingthrough the jig RENEWABLE:Types SF, SFC/SC/FC(carbide), and SFM (metric).

8 Replaceablebushing generally used with a liner bushing and lockscrew. Usewhen you expect to replace BUSHINGS during the tooling s lifetime, orwhen you want to switch BUSHINGS to perform multi-step operationswith the same tooling. SF BUSHINGS combine the benefits of older S-type slip-renewable and F-type fixed-renewable BUSHINGS : One sidehas a small recess for fixed mounting; the other has a locking recessthat allows the bushing to slip down, then lock in place by rotating and F types are now obsolete (except in carbide) and combinationSF BUSHINGS will be furnished at no extra 64thsof an inchLengthin 16thsof an inchID as4-placedecimal inchUSA P - 20 - 8.

Similar to an SF renewable bushing, butwith specially designed chip-breaking notches on the DRILL -exit end. Useto break up chips from tough, stringy materials, to reduce friction andheat buildup. Reduces bushing wear at the DRILL -exit end and reducesthe chance of tool or workpiece damage. A chip-breaker bushingshould extend beyond its liner to allow chips to escape. Chip breakersare also available on other bushing types such as P, H, and SELECTIONE&E SPECIAL PRODUCTS 7200 MILLER DRIVE, WARREN, MI 48092, 586-978-3377E&E SPECIAL PRODUCTS 7200 MILLER DRIVE, WARREN, MI 48092, 586-978-3377 Type SG.

10 Can be cast in place or potted, just as a diamond-groovebushing, or can also be pressed into an installation hole. Straight knurlprovides less resistance to axial loads than the diamond knurl on a DGbushing. Since the bushing s OD is not ground, keep the ID accuratelylocated during casting or potting to ensure accuracy in the finished GROOVE:EZ CAST LINER:BUSHING SELECTION3BU(12/03)AIR-FEED DRILL :DIAMOND GROOVE:DIRECTED COOLANT:TEMPLATE:Types DC, DCCH (chip breaker),DCL (liner), and DCHL (headliner). Similar to an SF renewable bushing, but with passages todirect coolant to the cutting area. This design is particularly good forwashing away chips, especially when ordered as the combinationDirected Coolant Chip Breaker (DCCH).
