Tighten the Left Alignment Plate bolts
to Table Mount, then push both the
Slide Plate and Right Alignment Plate
snug up against the Left Alignment
Plate, tighten the Right Alignment
Plate bolts to the Table Mount. Make
sure that Slide Plate can still slide
between the two Alignment Plates.
Tighten all bolts using the allen
wrench supplied.

Insert Centering Bit into the Drill Press
Chuck. Position Centering Tool over
Center Pin. Move Table Mount so the
Centering Bit will lower into the bit hole
of the Centering Tool. Tighten the two
exposed 1/4 inch bolts. Release
Alignment Pin, loosen Lock Down Bolt,
move the Slide Plate back and then
tighten the final two bolts. Remove
Centering Tool The tool is now ready for
radial distance drilling only.
Insert short Alignment Pin into the
Left Alignment Plate at the "For Black
Scale" position. Slide the Slide Plate
to the 5 inch mark of the Left
Alignment Plate. Seat the Alignment
Pin into the Slide Plate. Secure Slide
Plate into place by tightening the Lock
Down bolt.
Step 7 - Inserting Alignment Pin and securing Slide Plate
Step 8 - Centering Circle Guide to Drill Press Bit
Step 9 - Attaching Rotation Plate (for use with Degree Gears)

Basic Operations
Preparing Material
Drilling Holes in Material (without Degree Gears)
Remove any abrasive particles and/or spurs from face of material before rotating to prevent
damage to the surface of the Circle Guide tool.
The Circle Guide tool requires the rotation of material around a Center Pin. Please perform these basic steps
before drilling to prepare your material.
Drill a 1/8" (English) or 3mm (Metric) hole in material which will be the center point of your circle.
Drill the hole as perpendicular as possible to ensure precise rotation around the Center Pins.
Move the Slide Plate into desired position in order to set the radial distance. If using a set
measurement, insert the Alignment Pin into set measurement position and then tighten the Lock-
Down Bolt. If not using a set measurement, simply tighten the Lock-Down Bolt at current position.
Insert the desired drill bit into the Drill Press.
Turn on Drill Press and proceed to drilling a hole. Smoothly rotate material when drill bit is raised
to drill holes in circular pattern at the current radial distance. Repeat steps as needed.

Drilling Holes in Material (with Degree Gears)
Start by releasing the Alignment Pin and loosening the Lock-Down Bolt.
Insert the desired drill bit into the Drill Press.
Lift material off the Center Pin and place aside.
Move the Slide Plate into desired position in order to set the radial distance. If using a set
measurement, insert the Alignment Pin into set measurement position and then tighten the Lock-
Down Bolt. If not using a set measurement, simply tighten the Lock-Down Bolt at current position.
Turn on Drill Press and proceed to drilling a hole. Release the Rotation Alignment Pin and rotate
material when drill bit is raised. Lock into next Degree Gear slot and drill another hole. Continue
this process to drill holes in a circular pattern at the current radial distance. Repeat steps as
needed.
Attach the desired Degree Gear by first placing the material onto the Center Pin using 1/8"
(English) or 3mm (Metric) hole (bottom of material facing up). Place double-sided tape on smooth
side of Degree Gear and then place onto material using the Center Pin (gears facing up).
Place the Rotation Plate on top of the Slide Plate using Center Pin and ensure it seats into position.
Now place material back onto the Center Pin with Degree Gear facing down. Ensure the Degree
Gear seats into the designated hole in the Rotation Plate.
Insert the Rotation Alignment Pin into the Rotation Plate and lock into the Degree Gear slot.
NOTE: You can also mount using screw holes in Degree Gear instead of double-sided tape.

Step 1: Loosen the Lock-Down Bolt and release Alignment Pin.
Step 2: Move the Slide Plate to desired measurement position.
Step 3: Insert Alignment Pin into Slide Plate (should click into position).
Step 4: Tighten the Lock-Down Bolt and ensure the Slide Plate is held firmly in position.
Step 5: Perform drilling and repeat as necessary.
Step 1: Loosen the Lock-Down Bolt and release Alignment Pin.
Step 2: Move the Slide Plate to desired position.
Step 3: Tighten the Lock-Down Bolt and ensure the Slide Plate is held firmly in position.
Step 4: Perform drilling and repeat as necessary.
Tip 1:
Tip 2:
Tip 3:
Using Set Measurements
Using Infinite Variability
When using harder material, ensure the material does not overheat from excessive drilling as this
may cause damage to the surface of the Circle Guide tool.
Tips
To prolong the life span of the tool's surface, make sure to remove any abrasive particles and/or
spurs from face of material before rotating to prevent damage to the surface of the Circle Guide
tool.
When using large drill bits or Forstner bits, do not drill hole all the way through the material. First
start by drilling a pilot hole half way through the material, then flip over material and finish drilling.
This will also prevent drilling holes through the Circle Guide tool.
The Circle Guide for Drill Press provides the ability to set the Slide Plate into positions simply by moving Slide
Plate into desired position and ONLY tightening the Lock-Down Bolt. This provides "infinite" positions between
the minimum and maximum radial distance settings allowing operator to make incrementally small
adjustments or set Slide Plate into a position which cannot be locked into by using the Alignment Pin.
The Circle Guide for Drill Press provides the ability to lock in the radial distance at set measurements every
1/16" (English) or 2mm (Metric). This operation provides precise repeatability by allowing operator to recall to
a prior position.
