LUMBERJACK TOOLS CSK4000 Countersink Bit Set

ABOUT YOUR PRODUCT

Thank you for purchasing our Countersink Bit Set! The Countersink Bit is designed to taper mortise holes 60 o to match the shoulder profile cut by Commercial and Industrial Series Tenon Cutters. This results in a stronger joint and a more finished and professional look. The tool body is machined from a solid aluminum billet. The blade is laser cut, heat treated, and precision ground to provide years of service. The shank is machined from alloy steel to withstand the stresses of cutting.

Our lifetime guarantee covers the tool body and shank. The blade is covered for breakage for 90 days from the date of purchase under normal working conditions. Blades will dull faster when cutting hardwoods versus softwoods (peeled or unpeeled). Soil and other abrasive substances will reduce blade life and are not covered under this warranty. When making a claim, you must show proof of purchase from an authorized distributor. This guarantee is valid only to the original buyer, not for tools sold secondhand, used, or sold “as is” to a second party.

WHAT’S INCLUDED

Note: Images are not to scale.

SET UP

Install Blade

• a. Place the TB3125 Blade in the pocket and loosely attach with screws.
• b. Use one shim to space the blade against the countersink.
• c. Hold the blade in place with a piece of wood while securing screws.
• d. Remove shim.

CAUTION! BLADE VERY SHARP!

Adjust Blade

The graphic to the right displays what happens to cutting performance by adjusting the blade.

IMPORTANT
Correct blade offset is critical for smooth cutting.

• If cutting is too aggressive (too much bite), use life whims.
• If cutting is too shallow (not enough bite), add more shims.
• Folded paper works great as a shim for fine-tuning

Install Bushing

• Install the bushing on the bottom of the Countersink using the shoulder screw.

Tip
We recommend a low RPM, single-speed, corded drill. Install the correct bushing for the mortise hole (pg. 5) and attach the drill to the shank.

Tip
Use a drill press or Drill Sergeant to drill straight mortise holes.

IMPORTANT!
The Mortise hole must be straight before usingthe countersink. Irregular holes will cause the countersink bushing to bind and will prevent the countersink from cutting properly.

TROUBLESHOOTING

PROBLEM	CAUSE	SOLUTION
•  Not countersinking mortise hole.	•  Blade not offset far enough from the tool body.	•  Use Blade Shim to offset the blade from the tool (Pg. 5).
	•  Attempting to countersink crooked mortise hole.	•  The countersink only works on straight holes.
	•  Using wrong wrong-sized bushing.	•  Measure the mortise hole and match it to the correct bushing.
• Takes too much of a “bite”.	•  Aggressive cutting from blade offset.	•    Adjust the blade using one or no Blade Shims (Pg. 5).
•  Shoulder Screw is hard to remove.	•  Installed without applying anti-seize to threads.	•  Apply anti-seize to screw threads before installing.
•  Drill stops while countersinking mortise hole.	•  Using a variable speed drill.	•  Make sure you are using a single-speed drill with low RPMs.
	•  Blade bite is too aggressive.	•  Move the blade further back into the blade pocket (Pg. 5).
•  Drill spins, but the countersink stops cutting deeper.	•  Countersink pocket full of chips.	•   Carefully remove chips from the countersink with a screwdriver.
