Morris Wood Tool is pleased to
present the following information to assist you in determining the proper
bit point to use in a given situation.
STANDARD POINTS
|
|
BRAD POINT
|
The Brad Point is the preferred point for
most machine boring operations in wood and some plastics. The
center point holds and centers the bit while the outside lops or
spurs score the wood in advance of the main cutting edges.
This produces a smooth hole in most woods. It is the best
point to use for both cross grain boring and for dowels. When
through hole boring it will cause some slight split out on the back
side unless a backing board is used. |
|
DRILL
OR TAPER POINT
|
Morris Wood's Drill Point wood boring
drills have a 90-degree angle and are mainly used in cross grain
drilling. They are also excellent for end grain boring and
some hole applications.
|
|
RIGHT
& LEFT HAND DRILLS
 
|
Hold your drill up to the above illustration and
notice which drill has the flutes pointing the same way as yours.
Most standard drill presses and boring machines
rotate Right Hand. Some machines with multiple spindles will
have both Right Hand and Left Hand spindles. If all spindles on a
machine rotate the same direction, you can be 99% certain that all
are rotating Right Hand.
Drills will not be made with threads the opposite
rotation from the flute.
|
| SPECIAL PURPOSE POINTS |
|
END GRAIN POINT
 |
The End Grain point is used when a Brad
Point drill is desired for boring end grain. The reason that many
Brad Point drills tend to run out and burn in end grain is that the lips
are trying to follow the grain. Our End Grain point does not have lips and
the clearance angle of the main cutting edges is changed slightly.
This point bores straight and clean in most woods. |
|
V-POINT
|
The V or Fishtail point is used for
boring on an angle in the wood. It will not walk or travel on
the surface of the wood, as a taper point drill tends to do.
|
|
THRU-HOLE
POINT  
|
The Thru-Hole point is a sharp 60 degree point which
is used when going all the way through the wood without any
splitting on the back side.
|
|
HARDESTY HEAD |
Sometimes when boring stacked or laminated material
a button will form on the end of a standard brad point, which
prevents further drilling. The Hardesty Head is a multi angle Brad
Point that allows the drill to break up and remove the material
before it can form a button. |
