Frequently Asked Questions for Drilling

What type of grease can I use on the 1318 DrillMate Guide Bars?

Silicone based WD-40 is preferred, so there is no long-term damage done to the guide bushing in the Guide Head.

What size drill bits does the 1362 DrillBlock accommodate?

The DrillBlock will accommodate drill  bit sizes: 4mm, 5mm, 6mm, 8mm, 10mm, and 12mm.


Why are the holes slightly off angle when using a Forstner bit with the DrillMate?

When using the DrillMate with a Forstner bit or boring bit, you will need to remove the spring to reach proper drilling depth.


Why isn’t my bit penetrating the wood?

If you are trying to go through thicker material, the spring needs to be removed as the spring limits the travel.


What are the differences between the 1318 DrillMate and 1368 DrillMate?

There are a few differences between the two DrillMates. The main difference is how the drill attaches to the unit. The drill guide head on the 1318 DrillMate is compatible with 3/8” and ½” drills and the drill chuck connects to the shaft of the DrillMate. Whereas 1368 accommodates drills with a 43mm collar and this mounts to the head, this unit does not have a chuck and uses the drills chuck instead. Secondly, the 1368 guide head can be locked with the s-knob; 1318 does not have this feature.

What is the best way to drill large holes with the DrillMate?

If you are using a large diameter bit, for safety and accuracy it is recommended to clamp the jig.


Can I swap out the 3/8″ chuck on the DrillMate for a 1/2″ chuck?

Unfortunately, the threads on the chucks are not compatible. 3/8” chucks have 3/8” x 24 thread, and 1/2” chucks have 1/2” x 20 thread.


What is the largest diameter hole saw one can use to make a 45º angle cut with the DrillMate?

For a 45° angle cut, the largest hole saw that can be used is 1-5/8″.

What are size drill bits does the 1312 DrillBlock accommodate?

The integrated solid metal drill bushing block offers the six most common drill sizes: 1/8″, 3/16″, 1/4″, 5/16″, 3/8″, and 1/2″.


Can the DrillMate be used to start holes in porcelain tile shower walls?

Yes, the DrillMate can be used to start holes in porcelain tile.


Is the bushing block in the 1312 DrillBlock heat treated (hardened)?

Yes, the metal bushing block in the DrillBlock is heat treated.


Does Milescraft make a 1/2″ chuck that will fit the DrillMate?

If you would like to use a larger chuck or drill bits larger than the Milescraft 1318 DrillMate allows, Milescraft manufactures the 1368 DrillMate. For more information on this product, please click here.


What should I do if more horizontal depth is required than the thickness selector cam permits?

It may be necessary to remove the thickness selector assembly (red knob, spring, and cam) from each end of the metal frame to permit a deeper location of the frame/template.  Of course, doing this eliminates the automatic parallel alignment capability of the metal plate, so you must measure carefully to be sure the distances to the holes are correct before attaching the plate to the door or frame.  Be sure to re-install the thickness selector cam assemblies to the metal plate when that unusual job is completed, so the parts do not get lost.


What is the difference between the Drill90 and the Drill90PLUS?

The Drill90PLUS is the newer, upgraded version to the original Milescraft Drill90. This completely new design has an ergonomic body design with removable, dual position handle, for optimal support and capability to drill in hard-to-reach spaces. It has an enhanced, all-metal drive with bearings providing longer life and durability. The Drill90PLUS comes with a 3/8” keyless chuck, whereas the Drill90 has a keyed chuck. Drill90PLUS is compatible with most drill accessories including spade bits and hole saws. Drill90PLUS has a minimum reach of 4″ whereas the Drill90’s minimum reach is 5″. This drill attachment now gives you the ability to drill into even tighter spaces.


Why are the StubbyBits slipping?

Certain ball bearing hex connectors do have issues retaining the bit but the wire type ones work well. These StubbyBits were designed for use with the Milescraft line of Right Angle Drilling Products, making getting to those hard to reach spaces even easier.
