The Dexter mat cutter is an efficient tool for accurately cutting straight or bevel edge mats. With little practice, create professional looking mats without ragged and untidy edges. It is an easy to use safe tool that saves a great deal of time, money, and effort. Made in the USA, it is shipped with five #3 Dexter blades.
Dexter Mat Cutter Instructions
Needed Equipment: Dexter mat cutter, drawing board (or surface), metal t-square
(or straightedge), pencil, tape, and under padding (corrugated or plain
cardboard) Important to place between mat & drawing board so drawing board is
- 1. Tape the cardboard under-padding securely to the drawing board
- On the BACK of the mat board, measure and mark with pencil lines the
area to be cut out. Intersect the lines at each corner for starting points.
Important cutting the mat board from the back eliminates scuffing or marring
of the face (finished) side of the mat.
- Place a Dexter #3 mat cutter blade on the angled slot for bevel cuts or
in the perpendicular slot for straight cuts. The cutting edge of the blade
should be facing the direction in which you choose to cut.
- To set the correct blade cutting depth place a small piece of scrap mat
board against the underside of the mat cutter. Hold the mat cutter and the
board with one hand while forcing the blade point approximately 1/32″
through the mat board with the other hand. Tighten thumb screw to secure the
blade in position. Remove scrap piece of mat board.
- Place the mat board to be cut on the under-pad and position the T-Square
on it with the head of the T-Square at the base of the drawing board. Square
up the vertical pencil line on the mat board so itís parallel to the
T-Square. Slide the T-Square away from the drawn line to allow the mat
cutter to be positioned for the first cut. Maintain pressure on the T-Square
to prevent movement and to keep the mat board square at all times.
- After completion of the cut, turn the mat board clockwise 90 degrees.
Realign the vertical pencil line with the T-Square and make the next cut
using the same method as previously indicated. The results should give you
professional looking bevel edges every time.
- When mat cutting is finished, loosen knob, pull blade back from cutting
position and retighten for safety and to prevent broken points. For best
results always use a sharp Dexter #3 mat cutter blade in either the Dex or
Important Cutting Techique
For best results, cut
only in a North (push-up) or South (pull down) direction. Cutting from left to
right or vice-versa invariably leads to the T-Square slipping which produces
Cutting Toward North to South
- Right handed: If you choose to cut by drawing the mat cutter toward you
and you are right handed, insert the point of the blade into the mat board
approximately 1/16″ above the intersecting lines at the upper left-hand
corner of the drawn guidelines.
- Left Handed: If you are left handed, insert the blade point in the mat
board in the same manner in the upper right-hand corner. The straight edge
of the T-Square is now moved up against the blade side of the mini cutter.
Press the T-Square securely against the mat board with one hand while
drawing the mat cutter toward you with the other.
Cutting Away South to North
If you choose to cut by pushing the mat cutter away from you, reverse
the blade position in the angled slot of the Dex or rotate the Mini 180
degrees and begin the cut at the lower corners of the guidelines.
- If right handed person start cuts at the lower right corner.
- If left handed person start cuts in the lower left corner
Constant pressure must be applied to the mat cutter to keep it firmly
against the T-Square and to keep the blade point continuously penetrating
the mat board for a straight and even bevel cut.
