Trade Tip

Use the DM 4243 Counterbore tool to prepare the hole for this wood plug

Do not over tighten the screw or you will break the underside of the decking.

Always run a second drill bit to set the depth of the screw after the first preparation with the Counterbore tool.
When starting the hole scribe the surface with the Counterbore tool first, then apply downward pressure to cut hole – this will prevent chipping of the surrounding surface. When you get the set depth of the hole the black ring on the bottom of the tool it can leave a small black mark – do not worry as this gets sanded when the plug is trimmed. Key is – do not overdrive the tool and this will minimize the black ring mark.

Be sure to control the direct cut and withdraw the same so you do not break the drill bit – remember when drilling like this the drill bit will get hot and break if you twist the drill in and out.

Clean out hole prior to fixing the screw.

Simply roll the bottom of the plug in the Ultraset Glue then tap into hole – leave for 24 hours to cure then trim and sand.

You can adjust the collar of the counterbore tool to with make deeper or leave it as the factory setting will leave the plug 2mm proud so you can trim off after 24 hours.

When replacing the drill bit and BEFORE you loosen the grub screws cut a fine mark on the collar of the BORE section so you will have a precise mark to re set the outer crown back onto after the drill bit is refitted. Purchases of extras are often required when screws are damaged or lost – because the screw count equals the biscuit count often screws are dropped on the ground, left in nail bags etc, then simply buy an extra pack as required.
