What ACRA-CUT does

ACRA-CUT, Inc. is a privately held medical device manufacturer founded in 1981 and headquartered at 989 Main Street, Acton, Massachusetts, that researches, develops, and manufactures automatic-releasing cranial perforators and related neurosurgical instruments. The company's core technology is a patented cammed-lug release mechanism in which the inner drill advances less than 1mm before automatically disengaging, eliminating the risk of dangerous penetration through the skull. Its flagship Smart Drill — featuring a 14mm outer drill and 9mm inner drill — is positioned in company materials as the gold standard worldwide for automatic-releasing cranial perforators and is rated for skull thicknesses as thin as 1.5mm, with every disposable unit pre-tested through seven drilled holes before shipment.

The product ecosystem extends beyond the Smart Drill to include disposable and reusable cranial perforators in pediatric and adult sizes (8mm/5mm through 14mm/11mm), the ACRAGUN Scalp Clip System (reusable gun with disposable preloaded clip cartridges in serrated or straight jaws), sixteen craniotomy kits, hand instruments (Baker and Standard Dura Separators, Bone Pad Removers with titanium handles), and Disposable Distraction Screws for anterior cervical fusion sold in individual or 10-pack sterile blister packs. The company is ISO 13485:2016 certified for its quality management system covering design and manufacture of cranial perforators and related surgical instruments, and holds an EC Certificate evidencing EU MDR compliance.

ACRA-CUT operates a sales-led, direct-distribution model that targets neurosurgeons, neurosurgical departments in hospitals, and medical device distributors. Sales and service inquiries are captured through the corporate website and a toll-free 1-800 line, with the company explicitly identifying physician/healthcare professional and distributor as its contact-form segments. Pricing is quote-based and not publicly disclosed; the company markets both disposable and reusable hardware to capture procedural and capital-equipment revenue. In March 2026, Nakanishi Inc.'s U.S. subsidiary NSK America Corp. agreed to acquire ACRA-CUT (alongside precision manufacturer Intech) to integrate it into Nakanishi's Surgical Business as a second-tier subsidiary, with the combined deal explicitly intended to enable local North American production to mitigate U.S. tariff exposure.

Products and services

• Smart Drill Automatic-Releasing Cranial Perforator Automatic-releasing cranial perforator used by neurosurgeons and OR teams during craniotomy, burr-hole, biopsy, and shunt procedures; inner drill releases automatically after less than 1mm of forward travel to prevent intracranial penetration, operates safely on skulls as thin as 1.5mm, and creates a protective bone pad shielding the dura.
• Disposable Cranial Perforators Single-use automatic-releasing cranial perforators for hospitals and surgical centers performing high cranial-access volumes; eliminates per-case sterilization and ensures a clinically tested device for each procedure.
• Reusable Cranial Perforators Multi-use automatic-releasing cranial perforators designed for hospital sterile-processing workflows; provides the same patented cammed-lug safety performance as the disposable version across multiple reprocessing cycles.
• ACRAGUN Scalp Clip System Applicator system for scalp clips used by neurosurgeons to achieve rapid, consistent hemostasis of the scalp during and after cranial access procedures.
• Craniotomy Kits Procedure kits that bundle ACRA-CUT perforators and related accessories into a single ready-to-use set for craniotomy cases, streamlining OR setup and supporting hospital standardization.
• Baker Dura Separator Specialty neurosurgical instrument used to gently separate the dura from the inner table of the skull during cranial access, supporting safer dissection prior to opening of the dura.
• Standard Dura Separators Standard neurosurgical dura separators for separating the dura from the skull inner table during cranial-access procedures.
• Bone Pad Removers Hand-held neurosurgical instrument used by surgeons to remove the protective bone pad created by the Smart Drill at the conclusion of the perforator step.
• Disposable Distraction Screws Single-use distraction screws used by spine surgeons during anterior cervical fusion procedures to establish and maintain disc-space distraction prior to graft and plate placement.
