Description
Product Overview
The Dynabrade Dynafile II is engineered for professionals who demand precision and speed in abrasive operations. Powered by a 0.5 hp pneumatic motor that spins up to 20,000 RPM, the tool delivers consistent cutting power across a variety of materials, from metal to wood and composites. Its 7° offset handle positions the motor away from the operator’s hand, reducing vibration and improving control during extended use.
Constructed from a high‑strength aluminum/composite housing, the Dynafile II balances durability with a lightweight feel, weighing just 2.8 lb (1.27 kg). The design incorporates a 360° pivoting grinding head, allowing the belt to be positioned at any angle without sacrificing stability. The belt guard is easily removable, providing quick access for belt changes and maintenance. The tool accepts ¼‑¾” × 18″ abrasive belts, covering a broad spectrum of grit types and applications.
Every component of the Dynafile II is built to withstand the rigors of daily shop floor use. The front exhaust directs dust away from the work area, keeping the operator’s line of sight clear and the workspace cleaner. The included contact arm (part 11206) ensures precise belt tracking, reducing slippage and extending belt life. All parts are designed for rapid disassembly, making routine cleaning and part replacement straightforward.
Beyond its mechanical strengths, the Dynafile II benefits from Dynabrade’s lifetime warranty program. By registering the tool at www.dynabrade.com, owners secure a lifetime guarantee against defects in workmanship and materials, reinforcing the brand’s confidence in the product’s longevity.

Usage
This belt tool excels in environments where precision grinding, deburring, and polishing are required. Whether you are preparing weld seams, smoothing rough edges on fabricated metal parts, or finishing wooden surfaces, the Dynafile II provides the torque and speed needed to achieve a smooth finish quickly. Its compact size and offset handle make it ideal for tight spaces, such as inside chassis, around pipework, or in confined assembly lines.
Because the tool is air‑powered, it eliminates the need for batteries or cords, granting the user unrestricted mobility on the shop floor. The 7° offset design reduces operator fatigue during prolonged sessions, while the ergonomic grip ensures a secure hold even when wearing gloves. The tool’s versatility also extends to automotive repair shops, where it can be used for bodywork sanding, brake rotor resurfacing, and engine component preparation.
When paired with the appropriate abrasive belt, the Dynafile II can achieve surface finishes ranging from coarse material removal to fine polishing, making it a single‑solution tool for multiple stages of a project.
