Review: Flex is the way! - ⭐️⭐️⭐️⭐️⭐️ Absolute Beast of a Grinder! This Flex grinder is an absolute beast—just like every other Flex tool I’ve bought. It cuts and grinds with power and precision, and the battery life is excellent. What really sets it apart is that it doesn’t auto shut down at the slightest bind like some other brands I’ve used. I appreciate that it comes with a wrench too—even though I usually tighten and loosen by hand, it’s great to have for those extra snug moments. Hands down, this is the best grinder I’ve ever used—better than Milwaukee, Makita, or Ridgid in my experience. I highly recommend this one and honestly, all Flex tools. They’ve earned my trust! Review: Great grinder. - This grinder is really nice. The handed is ok i wish it was threaded the other way around as i find myself gripping towards me which loosens the handle. The variable speed is sweet and really helpful when I need lower speed and it isnt super loud as my other grinder which is also brushless and battery powered. Overall great kit and won't disappoint. I don't abuse my tools so I can't say much on durability but I would say its a great value especially if you get it on sale during holidays. ## Features - THE FLEX ADVANTAGE - 20% more power with 24V lithium, 25% longer runtime with THERMA-TECH heat management, up to 50% faster charging with high-power, dual fan chargers - SENSOR-FREE BRUSHLESS MOTOR - Every FLEX 24V tool is built around an intelligent sensor-free brushless motor designed to eliminate friction and optimized for higher efficiency and power - UNMATCHED POWER - Up to 10,000 RPM - TOUCH CONTROL - Adjustable speeds match the application for optimal precision - ANTI-KICKBACK - Advanced braking technology lets you work with confidence - ONE-STEP GUARD ADJUSTMENT - Fast guard adjustments for every application - ERGONOMIC DESIGN - Slim grip for improved comfort - FLEX 24V CROSS-COMPATIBILITY - Compatible with all FLEX 24V batteries, chargers, and tools - FLEX 5-YEAR LIMITED WARRANTY - Register your new FLEX tool, battery, or charger within 30 days of purchase to receive a 5-year limited warranty; 3-year limited warranty without registration ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CBB7W2FK | | Best Sellers Rank | #84,736 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #80 in Power Angle Grinders | | Brand | FLEX | | Brand Name | FLEX | | Color | Grey/Black | | Compatible Disc Grinder Tool Models | Flex FX3171A-1C | | Customer Reviews | 4.8 out of 5 stars 62 Reviews | | Global Trade Identification Number | 20840163200190 | | Horsepower | 0.21 hp | | Included Components | Battery, Battery Charger | | Item Dimensions L x W x H | 12.6"L x 4.1"W x 3.1"H | | Item Type Name | DISC_GRINDER_TOOL | | Manufacturer | FLEX | | Manufacturer Part Number | FX3171A-1C | | Material | Plastic | | Material Type | Plastic | | Maximum Rotational Speed | 10000 rpm | | Model Number | FX3171A-1C | | Number of Items | 1 | | Power Source | Battery Powered | | Product Dimensions | 12.6"L x 4.1"W x 3.1"H | | Style | Paddle Switch - w/Battery and Charger | | Style Name | Paddle Switch - w/Battery and Charger | | UPC | 840163200196 | | Unit Count | 1 Count | | Voltage | 24 volts | | Wattage | 160 watts | ## Product Details - **Brand:** FLEX - **Material:** Plastic - **Power Source:** Battery Powered - **Product Dimensions:** 12.6"L x 4.1"W x 3.1"H - **Style:** Paddle Switch - w/Battery and Charger ## Images ![FLEX 24V Brushless Cordless 5-Inch 10,000 RPM Variable Speed Paddle Switch Angle Grinder Kit with 5.0Ah Lithium Battery and 160W Fast Charger - FX3171A-1C - Image 1](https://m.media-amazon.com/images/I/619-h1ZXhXL.jpg) ![FLEX 24V Brushless Cordless 5-Inch 10,000 RPM Variable Speed Paddle Switch Angle Grinder Kit with 5.0Ah Lithium Battery and 160W Fast Charger - FX3171A-1C - Image 2](https://m.media-amazon.com/images/I/61PZgpsFgpL.jpg) ![FLEX 24V Brushless Cordless 5-Inch 10,000 RPM Variable Speed Paddle Switch Angle Grinder Kit with 5.0Ah Lithium Battery and 160W Fast Charger - FX3171A-1C - Image 3](https://m.media-amazon.com/images/I/61MoxqVenuL.jpg) ![FLEX 24V Brushless Cordless 5-Inch 10,000 RPM Variable Speed Paddle Switch Angle Grinder Kit with 5.0Ah Lithium Battery and 160W Fast Charger - FX3171A-1C - Image 4](https://m.media-amazon.com/images/I/51M-PZJbKmL.jpg) ![FLEX 24V Brushless Cordless 5-Inch 10,000 RPM Variable Speed Paddle Switch Angle Grinder Kit with 5.0Ah Lithium Battery and 160W Fast Charger - FX3171A-1C - Image 5](https://m.media-amazon.com/images/I/612FzBOJZUL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Flex is the way! *by C***D on August 3, 2025* ⭐️⭐️⭐️⭐️⭐️ Absolute Beast of a Grinder!
