Forster Neck Reamer Instructions Manual

							The Forster Neck Reamer will remove excess brass from the inside neck walls of cartridge cases.
High-grade tool steel and a staggered-tooth design enable the Forster Neck Reamer to cut brass
smoothly without chatter. Forster Neck Reamers are ground .0025”-.003” larger than maximum bul-
let diameter, therefore neck reaming should be done after the case has been fired with a full
load and before the neck or full length sizing operation.

Begin by fastening your Forster Case Trimmer securely to a bench or board to allow the free use
of both hands. Insert the shank of the Neck Reamer into the pilot hole of the cutter shaft. Tighten the
set screw. Select the proper collet for the case you will ream. Remove the collet screw from the col-
let housing. Apply a small amount of grease to the front face, tapered portion and base of the collet.
Insert the collet into the collet screw. Insert the collet and collet screw into the housing. With tension
on the collet released, insert the base of the case into the collet. To aid in centering the case, start
the Reamer into the case neck. (Do not force the Reamer against the brass.) Push the base of the
case firmly against the shoulder of the collet, then tighten the collet screw with your other hand.
Using a light, inward pressure and smooth turning action with the crank, ream the case neck to the
desired depth. Continue to turn the crank while withdrawing the Reamer from the case neck. Finally,
brush the chips away from the Neck Reamer after each case is reamed to ensure a fine finish. The
case is now ready for the neck or full length sizing die.
Neck Reamers can also be used with the Forster Power Case Trimmer (PT1010). However, when
used with the Power Case Trimmer, the lowest spindle speed should be used.
