Fastmount 16.8 mm step drill bit is used to install Standard Profile Series Female Clips, item SLPC-F1, so it creates the specific hole geometry those panel mounting clips require for consistent engagement. The drill is identified as manufacturer part CT-13A, giving installers a clear match when they need to spec or re-order the same tool for repeat panel work. As part of a panel assembly fitting system, this drill supports the mounting workflow where accurate clip positioning and repeatable hole size directly affect how removable panels sit on the structure. When this drill is used for the SLPC-F1 clips, the resulting holes are tailored to the Fastmount profile, which helps panels align predictably in service. That fit relationship between the drill and the clip matters on larger runs, where even small deviations can telegraph through as uneven reveals along seams.
The Fastmount CT-13A step drill is specified as a 16.8 mm carbide step drill for SLPC-F1, so it is dimensioned around that Fastmount Standard Profile Series Female Clip pattern. Because it is meant for SLPC-F1 clip installation, the bit sets up the substrate with holes tailored for those clips rather than a generic fastener. Being part of a panel mounting system, the drill plays a role in how quickly crews can move from drilling to clip insertion while keeping hole sizing uniform. When installers follow the SLPC-F1 workflow with this drill, they gain a dedicated cutting tool built around the same profile that the clips are engineered to fit.
The Fastmount 16.8 mm step drill bit is used to install Standard Profile Series Female Clips, item SLPC-F1, so it is applied wherever those clips are being used to mount panels. Because the drill is designed to drill holes into fiberglass laminates, it fits projects where composite panels must be removable yet secure on a Fastmount system. The same drill is also designed to drill into carbon fiber laminates, giving shop teams a single tool for different composite skins on similar structural frames. In addition, it is designed for kevlar laminates, extending its use to high-performance panels that still rely on the Standard Profile Series Female Clips for mounting. These material capabilities allow one drill to support mixed-material jobs while keeping the SLPC-F1 clip interface consistent across all panel types in the run.
The CT-13A drill is described as a 16.8 mm carbide step drill for SLPC-F1, so its stepped geometry and diameter are tuned to that panel mounting task rather than general drilling. Because it is carbide tipped, the cutting edges are suited to drilling into fiberglass, carbon fiber, and kevlar laminates, which helps maintain cutting performance over repeated holes in abrasive composites. When installers use a carbide tipped step drill on these laminates, the bit geometry supports clean hole formation that respects the Fastmount clip profile, which helps the Standard Profile Series Female Clips seat correctly. The fact that this tool is aligned to SLPC-F1 within a panel mounting system means hole shape, depth, and diameter are all working toward the same goal: letting the clip and panel interface behave as designed over the life of the installation.
The Fastmount CT-13A step drill is used to install Standard Profile Series Female Clips SLPC-F1, so it prepares holes specifically shaped for those panel mounting clips.
The 16.8 mm carbide step drill is specified for Standard Profile Series Female Clips, item SLPC-F1, aligning the drilled hole with that particular Fastmount clip style.
The drill bit is designed to drill holes into fiberglass laminates, so it supports installing SLPC-F1 clips on fiberglass panel work.
The CT-13A is designed to drill holes into carbon fiber laminates, allowing SLPC-F1 clip mounting on carbon fiber panel assemblies.
The step drill is designed to drill holes into kevlar laminates, so it fits SLPC-F1 clip installations on kevlar-based panel systems.
The drill is carbide tipped and tuned as a 16.8 mm step drill for SLPC-F1, supporting hole quality in abrasive laminates while matching the Fastmount clip profile.
The Fastmount 16.8 mm step drill bit ties directly to Standard Profile Series Female Clips SLPC-F1, so it lines up with installers who are committed to that panel mounting system. Its role as a 16.8 mm carbide step drill for fiberglass, carbon fiber, and kevlar laminates means one tool can support composite panel runs using those materials while still honoring the Fastmount clip geometry. For shops and installers working with Standard Profile Series Female Clips on composite skins, this CT-13A drill provides the dedicated hole form the system expects, helping panels mount consistently from the first opening through the last.
