Portable, modular, precision drill fixture

Vac-Exact

A modular, portable drilling fixture that brings precision directly to the workpiece. Using a vacuum-locking locator and a magnified bombsight for alignment, it holds steady on flat or curved surfaces so every hole is perfectly centered and perpendicular.

For technicians, this means fewer errors, less fatigue, and faster, cleaner results. Vac-Exact simplifies complex drilling tasks, reduces the risk of damage and FOD, and makes precision accessible anywhere—from major MRO operations to small maintenance shops.

Accepts industry-standard slip-fixed renewable bushings, making Vac-Exact compatible with nearly any drill bit size. Use what you already have in the shop, or order custom sizes for specialized applications.

Secures the drill bushing to the locator, ensuring perfect alignment and stability. This adapter bridges common bushings with Perfect Point’s proprietary fixturing for consistent, repeatable accuracy.

Powered by an external venturi vacuum module connected to shop air, the locator clamps firmly to flat or curved surfaces. A manual lever/button vents suction for repositioning, then re-engages to lock in place—no motors or electronics required.

An optional shop-vac connection clips onto the locator body, helping remove chips and dust as you drill. It reduces cleanup effort and lowers FOD risk, while keeping the system lightweight and portable.

Components & Options

The right setup for every job

Offset Vacuum Locator

Designed for drilling on curved skins, corners, or hard-to-reach areas, the offset locator uses a spherical washer stack-up to adapt to surface angles while keeping the drill perfectly perpendicular. This flexibility ensures consistent accuracy on aircraft fuselages, nacelles, or any contoured structure where flat jigs won’t work.

Flat Vacuum Locator

A simple, lightweight option for flat or mildly curved surfaces. The flat vacuum locator locks firmly in place with minimal setup, making it ideal for high-volume or repetitive drilling tasks where speed and reliability matter. Technicians can position, clamp, and start drilling in seconds without complicated fixturing.

Bushings & Adapters

Vac-Exact uses standard slip-fixed renewable drill bushings held in precision adapters. Once the locator is locked in place, bushings can be swapped out for different drill bit sizes or reamers without moving the tool. This means the hole stays perfectly centered and aligned, even when stepping up sizes, saving time and preventing misalignment.

Location Devices

Interchangeable magnifying bombsights, reticle apertures, and precision dowel pins help center the locator exactly over the intended drill point every time. Whether aligning to an existing fastener hole or starting fresh, these devices give technicians the confidence that every hole begins in the right spot — eliminating guesswork and reducing rework.

Venturi Vacuum Module

Compact and maintenance-free, the venturi module provides steady vacuum power by plugging directly into standard shop compressed air. No electrical pumps or motors are needed. Once connected, it delivers reliable suction to the locator of your choice, making Vac-Exact easy to deploy anywhere with shop air access.

    Precision where it matters most

    Vac-Exact Use Case Scenarios

    From aircraft skin repairs to industrial maintenance, Vac-Exact locks in place and guides every drill for centered, perpendicular holes with less rework and cleaner results.

  • Aircraft Skin Repairs

    Keeping holes aligned on thin, curved skins is notoriously difficult. Vac-Exact locks to the fuselage surface and holds the drill perpendicular, preventing bit walk and reducing costly rework.

  • Pulling Holes (Correcting Misaligned Holes)

    When a hole is off-center or oversized, re-drilling can cause the bit to wander. Vac-Exact keeps the drill steady on the new centerline, making pulling holes straightforward and precise.

  • Fixture Replacement

    Large parts that don’t fit in a drill press often require complex, expensive fixturing. Vac-Exact replaces this setup with a lightweight, portable solution, bringing perpendicular accuracy directly to the workpiece and saving time on every job.

  • Engine Nacelle Maintenance

    Drilling or reaming holes in nacelle casings demands accuracy and cleanliness. Vac-Exact ensures concentric alignment while the optional debris attachment helps reduce chips around sensitive components.

  • Beyond Aerospace

    Vac-Exact’s benefits extend well outside aircraft maintenance. From automotive repair and restoration to industrial fabrication, energy, and maritime applications, it provides portable precision wherever traditional fixturing isn’t practical.
