| PRESS
FIT BUSHINGS: Designated as type P,
are the least expensive and most popular
bushings. Generally used in single step
drilling. Pressed flush in the fixture plate
they can be spaced closer together than
other types of bushings. Available as unground
with additional outside diameter stock. |
HEAD
PRESS SIT BUSHINGS: Designated as type
H, they can accept heavier axial loads than
type P bushings whether mounted with the
head above the fixture plate or recessed
into the fixture. Also available as unground
with additional outside diameter stock. |

|
| SLIP/FIXED
RENEWABLE BUSHINGS: Designated as type
SF, these bushings are mostly used when
the number of holes drilled will be greater
than the expected life of the bushing. Type
SF is also used when a hole is drilled,
then a reaming or tapping operation is required.
By slipping the bushing out of the liner
anther size may; be installed for the next
operation to be performed. Clamps or lock
screws are used to secure them in the fixture. |
FIXED
RENEWABLE BUSHINGS: Designated as type
FM, these bushings are mostly used when
the number of holes drilled will be greater
than the expected life of the bushing. By
slipping the bushing out of the liner another
size may be installed for the next operation
to be performed. Clamps or lock screws are
used to secure them in the fixture. |

|
| |
|
| LINER
BUSHINGS: Designated as type L, are
similar to press fit type bushings but are
pressed in the fixture to maintain precise
location for the slip fixed bushings. Their
hardened condition protects the fixture
form the wear of repeated bushing replacement.
These parts may be ordered as unground when
extra outside diameter stock is needed. |
HEAD
LINER BUSHINGS: Designated as type HL,
is used when excessive axial loads or pounding
would dislodge the headless liner. Type
HL may be used with the head projected above
the fixture or countersunk flush with the
top surface of the fixture. HL bushings
are available with extra stock on the outside
diameter when necessary, and ordered as
unground. Length is measured overall including
head. |

|
| UNILOCK
LINERS: Type UL is similar to the head
liner with the additional feature of a locking
lip projecting up to replace the necessity
of drilling, tapping and use of a lock screw
when using slip/fixed bushings. |
UNILOCK
LINERS DIAMOND KNURLED O.D.: Designated
as ULD. Their knurled outside diameter for
use in imbedment fixturing is their main
function. |
| |
|
|
|
|
| EZ
CAST LINERS: Designated type EZ-L, this
type liner has the lock screw positioned
for slip fixed bushing use in fiberglass,
laminated or similar type fixturing. The
EZ-L is positioned, then held in place with
epoxy or similar potting compound. |
SERRATA
PRES FIT BUSHINGS: Known as type SP.
These bushings have half length oversize
serrations for extra holding capabilities
in aluminum, masonite or wood fixtures. |
| |
|
|
|
|
| DIAMOND
GROOVE BUSHINGS: Designated as type
DG, these bushings may be sued in a cast
or potting application or pressed into soft
fixturing such as laminates or acryliccs.
Tyhis diamond knurled type holds better
when axial and rotational forces exist. |
SERRATA
GROOVE BUSHINGS: Designated as type
SG, these bushings may be used in a cast
or potting application or pressed into soft
fixturing such as laminates or acrylics.
|
| |
|
|
|
|
| TEMPLATE
BUSHINGS: Type TB bushings are for light
weight fixturing whose thicknesses range
from 1/16 to 3/8 inch thick. They have serrations
to add resistance to rotational forces and
an aluminum ring to clamp it firmly to the
template. |
CHIP
BREAKER BUSHINGS: When drilling material
producing long stringy chips, the chip breaker
feature is added to the exit end of the
bushings to assist in breaking up these
chips. The bushing projects beyond the fixture
to allow the chips to be broken and not
have to travel up the drill flutes. Add
CH after the ANSI code. Example: SF 88-22
CH 1" |
| |
|
| |
|
| DIRECTED
COOLANT BUSHINGS: Specially designed
for heavy drilling needing coolant to flush
the chips away from the drill and work piece.
These slip type bushings with coolant hole
liners ensure coolant flow directly on the
drill without the inconvenience of flexible
lines. Add DC after the ANSI code. Example:
SF 48 -16 DC 1/2" |
DIRECTED
COOLANT LINERS: For use with directed
coolant bushings. They are available as
headless or with heads, and should be ordered
the same length as the bushings to work
properly. Add DC after the ANSI code. Example:
L-64-16 DC. |

|
| COMBINATION
CHIP BREAKER DIRECTED COOLANT BUSHINGS AND
LINERS: These specialty type bushings
offer the best assistance in drilling difficult
material with the chip breaker extending
beyond the liners to help break up the chips
and the positive coolant flow to wash away
the chips and provide lubricity to the drill
making a very good combination frill guide. |
GUN
DRILL BUSHINGS: Used in gun drilling
machines such as EL Dorado, DeHoff and Drillmation.
Some machines use an SF type with an insert.
Designated GDI for the inserts and GDL for
the liner holding the insert. Other types
of one piece construction are GDB liner
and insert as one piece. DGDB deep hole
gun drill bushigns have a long guide projecting
beyond the chip box. Type GDH is for the
DeHoff machine with the insert at the end
opposite the head. |

| AIR
FEED DRILL BUSHINGS: Are available for
such tools as Busckeye, Aro, Gardner-Denver,
Quackenbush, DeSoutter and Ingersoll-Rand.
Threaded collars, shanks or tips and locking
devices for their use are available. |
OIL
GROOVE BUSHING: Oil groove bushings
are available in any ANSI style. They offer
complete positive lubrication and they are
available in 25 oil groove configurations
plus wipers at the ends if needed. |
