Halt Bit - 1/4" x 1.25"

Overhead anchor preparation in concrete ceilings requires controlled diameter and depth. Over-drilling slows production, increases bit wear, and may leave an anchor outside its specified installation conditions. Hook and Hanger distributes the ODM-250 for crews installing cable management and other commercial interior supports. Its depth-control design provides a repeatable stopping point without visual estimates overhead.

When you select the Halt Bit - 1/4" x 1.25", you are utilizing a tool engineered to deliver a perfect depth every time, eliminating over-drilling and offering a reliable solution that stands up to the heavy demands of professional installation work. Its 1/4-inch diameter and built-in stop create the intended 1.25-inch hole. We supply it for compatible eye wedge and I-Pin anchor work with an overhead drill machine.

What Is the Halt Bit - 1/4" x 1.25" Used For?

The ODM-250 controls hole preparation before a compatible anchor is driven and set in a concrete ceiling.

• Drills precise 1/4-inch holes using a compatible overhead drill machine.

• Uses an integrated depth stop to end drilling at 1.25 inches and prevent over-drilling.

• Prepares concrete for compatible 1/4-inch eye wedge anchors and 1/4-inch I-Pin anchors.

• Supports consistent holes across repeated ceiling-wire and overhead support points.

• Reduces reliance on hand-marked depth references during repetitive work.

• Provides repeatable preparation when the anchor, base material, and tool settings meet project requirements.

How to Install 1/4" Anchors Using the Halt Bit - 1/4" x 1.25"

First, confirm that the concrete, anchor type, required embedment, and planned attachment agree with approved project documents. Mark the overhead locations and establish the required work-zone controls. Fit the Halt Bit - 1/4" x 1.25" to a compatible overhead drill machine, hold the drill square to the ceiling, and drill a 1/4-inch hole until the depth control stops penetration. Withdraw the machine without widening the opening, then follow the hole-preparation directions in the anchor instructions.

Next, remove the bit and insert the correct SDS Plus installation tool into your hammer drill. Set the hammer drill to hammer-only mode. Place a pre-tied 1/4-inch anchor into the tool slot, align it with the opening, and hammer it into the hole. Pull down to set the connection as directed. Complete the required inspection before attaching supported services.

When your crew evaluates preparation tools alongside standard overhead drilling and anchoring operations, this method maintains uniform hole depths from one location to the next. Consistency supports predictable anchor seating, simplifies field checks, and limits unnecessary deck penetration across a large reflected ceiling plan.

Commercial ceiling frameworks may also use beam clamps, angle clips, or threaded rod fasteners, depending on the structural attachment and specified support method. These components are not interchangeable with concrete anchors. Hook and Hanger helps you identify hardware for the approved detail, while project documents determine selection, spacing, and allowable load.

Why Choose Precision Drilling Tools for Ceiling Grids?

A complex suspended ceiling layout may contain many support points for grid wire, electrical pathways, communications runs, and mechanical services. Consistent anchor depth matters because engagement begins with a correctly prepared hole. A depth-controlled bit gives each installer the same physical stop, reduces variation, and protects the planned embedment condition. Repeatable preparation supports the structural integrity of the specified connection while making production records, crew instruction, and installation review easier to manage.

The fixed configuration also gives your team a consistent tool reference for equipment lists and a defined size for submittals or work plans. Before drilling, verify the condition of the base material, anchor approval, edge distance, spacing, load limits, and jobsite safety requirements. 

Hook and Hanger also supplies purlin clips, j-hooks, extension poles, and eye lag screws for applicable overhead work. We offer these items so you can coordinate access equipment and attachment hardware with the system shown in your plans, supporting full project compatibility from drilling to the ceiling deck.
