The basis of the HIT-66 is it’s clamp system. All other tools in the HIT-66 family attach to these rubber-lined clamps. The clamps fit doors ranging from 1-1/4” to 2-7/8” and are machined from aluminum.

The HIT-66-100 is, for all intents and purposes, an installation template for any lock requiring a 160 or 161 prep. It can perform fresh installations or enlarge existing crossbores. It works on wood and steel doors and can accommodate 2-3/8″ and 2-3/4″ backsets. It features 5/16″ holes for through-bolts at the 6 and 12 o’clock positions. The latchbore can be drilled with either an auger, brad-point, multi-point, or hole saws with the supplied adapters.

The HIT-66-200 is an attachment that mortises pockets for mortise locks. It directly attaches to the HIT-66 clamp system and can be used in conjunction with nearly all other HIT-66 templates at the same time. This allows you to perform a fresh installation of almost all popular mortise locks currently on the market. It comes with a 1″ carbide-tip mortising bit along with stop collars.

Using the HIT-66

The HIT-66 is one of the easiest installation tools to use. In this example, I’m going to show you how it works by using the HIT-66-282 template for Schlage L Series mortise locks.
This door has a Schlage L9070 (Classroom function) mortise lock. It needs to be converted to a L9050 (Office/Inner Entry function). This means that the hole for the thumbturn hole needs to be drilled.

To start, the existing lock must be removed.

Once the lock is removed, we can begin attaching the HIT-66 and template. We start first by attaching the positioning plate. This helps orient the rest of the HIT-66 tool.

With the positioning plate install, we can now mount the rest of the HIT-66. The HIT-66 slides over the post of the positioning tool and is then pressed against the edge of the door. The clamps can then be tightened.

With the HIT-66 mounted, we can now drill. Since we only have to drill for the thumbturn, we identify that hole and drill.

It’s that simple and that quick. Professional quality results in seconds. Cylinder holes can be drilled as quickly and professionally as well.
