Sioux Tools Heavy Duty Right Angle Die Grinder

Description

Reach tight casting cavities using the Sioux Heavy-Duty Right-Angle Die Grinder to blend internal weld seams, port cylinder heads, and deburr machined steel forgings. Operating on 90 PSI shop air, the precision governed pneumatic motor spins 1/4-inch carbide burrs up to 18000 RPM through a 90-degree angle head. Toolroom machinists grind confined metal pockets smoothly. Sized for industrial grinding, the tool consumes 3.5 CFM at idle and 18 CFM under full spindle load.

Solid machined aluminum forms the slender grinder handle, wrapped in an ergonomic textured grip sleeve that isolates hands from cold motor exhaust. The 90-degree angle head encases spiral bevel gears machined from hardened alloy steel, supported by precision dual ball bearings. Sized for toolroom deburring, the bare right-angle grinder weighs 1.8 lbs, measuring 7.0 inches long with a 1/4-inch precision Erickson-style collet chuck, accepting standard 1/8-inch reducer bushings.

Internal Governed Spindle Bench Limits

Tachometer bench calibration verifies the internal speed governor maintains 18000 RPM free speed within two percent at 90 PSI dynamic line pressure, maintaining 16500 RPM under four pounds of heavy carbide burr cutting force. Spiral bevel gear backlash measures under 1.5 mils, eliminating gear chatter during heavy weld seam blending. Rear exhaust air routing keeps grinding dust blown away from the operator, holding noise levels below 79 dBA.

Key Features of Sioux Tools SDR10P

Toolroom machinists and aerospace fabricators buy Sioux Heavy-Duty Right-Angle Die Grinders to port engine heads and deburr precision aircraft forgings. Compare commercial pneumatic right-angle die grinder pricing to upgrade your metal finishing shop inventory.

• Internal speed governor maintains 18000 RPM spindle speed under heavy cutting loads, maximizing carbide burr removal rates cleanly.
• Precision 90-degree right-angle head reaches into confined casting cavities and internal pipe bores where straight tools cannot fit cleanly.
• Industrial-grade spiral bevel gears deliver smooth power transfer with minimal gear vibration and extended tool operating life cleanly.
• Heavy-duty 1/4-inch collet chuck grips tool shanks tightly with under 0.5-mil runout, preventing burr chatter and premature tool wear cleanly.
• Safety lock throttle lever prevents accidental tool startup when laid on metal workbenches or dropped into toolboxes cleanly.
• Rear exhaust deflector routes compressed air discharge away from workpieces, preventing airborne metal filings blow-back cleanly.

Toolroom Grinding Negative Selection Filter

The safety lock lever requires depressing the safety catch before engaging the motor, preventing accidental startups. Do not purchase this precision right-angle die grinder for heavy 7-inch weld cutoff wheels, stone masonry cutting, or running on small finish compressors lacking 4 CFM delivery. Routine care requires adding four drops of pneumatic motor oil into the air inlet daily before connection, greasing the angle head bevel gears weekly, and inspecting collet chucks for runout.
