Specifications: Air Inlet: 1/4" NPT, Chisel Shank Size: 0.401”, Piston Stroke: 3-5/8", Stroke Speed: 2,100 BPM, Net Weight: 5.31 LB, Length: 10.25", Hose Size: 3/8", Air Pressure: 90 PSI Review: Highest Value Air Hammer - This air hammer is worth it's weight in gold. I purchased it because of the Torque Test Channel on YouTube and it has proved itself multiple times in just a few days of use. I stayed away from air hammers because of their price and I've been getting along fine using my 4 pound sledge and pickle fork set. After watching several videos and other technicians recommending getting an air hammer I purchased the 401K Thor. The 498 Thor was tempting, but for regular automotive work you truly cannot beat the price of this tool. It is a big air hammer but is definitely extremely well made, functions perfectly, and saves an incredible amount of time and effort. Review: Hits Hard! - Great Air Hammer! Knocked all the rust out of a set of frozen rotors. Hits Hard. Highly recommended. ## Features - Maximum power .401" shank air hammer for heavy duty automotive and industrial applications - Specifically developed THOR model with stroke length and ported valvebody for power that matches or beats the top premium options from tool trucks - Newly designed tilt valve trigger for sensitive power adjustment at your finger tips - Features internal brake vibration damping system for less fatigue - No nonsense design: A rotatable forward grip, sensitive trigger and industry leading power - Includes quick change chuck, 10.25" length, Hi-Flo fittings suggested - Bare tool, bits sold separately ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01JBNJCAA | | Additional Features | Durable | | Best Sellers Rank | #175,833 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #279 in Riveters | | Brand | AP Astro Pneumatic Tool Company | | Brand Name | AP Astro Pneumatic Tool Company | | Color | Gray | | Colour | Gray | | Compatible Devices | Air compressors | | Customer Reviews | 4.3 out of 5 stars 197 Reviews | | Drill Type | Hammer Drill | | Drilling Capacity Metal | 0.4 Inches | | Drilling Capacity Wood | 0.4 Inches | | Global Trade Identification Number | 00745227080557 | | Included Components | 0.401" Shank "THOR" Long Barrel Air Hammer/Riveter | | Included components | 0.401" Shank "THOR" Long Barrel Air Hammer/Riveter | | Item Dimensions L x W x H | 10L x 10W x 10H millimeters | | Item Type Name | Astro Tools 401K 0.401" "THOR" Long Barrel Air Hammer/Riveter | | Item Weight | 2.85 Kilograms | | Manufacturer | Astro Tools | | Manufacturer Part Number | 401K | | Material Type | Chrome Vanadium Steel | | Maximum Chuck Size | 0.4 Inches | | Maximum Power | 0.4 Horsepower | | Maximum Torque | 120 Foot Pounds | | Maximum chuck size | 0.4 Inches | | Model Number | 401K | | Power Source | air_powered | | Power source | air_powered | | Special features | Durable | | Torque | 120 Foot Pounds | | UPC | 745227080557 | | Unit Count | 1 Count | ## Product Details - **Brand:** AP Astro Pneumatic Tool Company - **Colour:** Gray - **Included components:** 0.401" Shank "THOR" Long Barrel Air Hammer/Riveter - **Maximum chuck size:** 0.4 Inches - **Power source:** air_powered ## Images ![Astro Tools 401K 0.401" "Thor Super Duty Long Barrel Air Hammer/Riveter - Image 1](https://m.media-amazon.com/images/I/51vMWliw8HL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Highest Value Air Hammer *by L***E on 18 April 2025* This air hammer is worth it's weight in gold.
