From the Manufacturer Bosch Keyless Chuck Adaptor. Review: Need to drill big holes? Drive big lags/bolts? Buy this!!! - Amazing! I can’t afford a new hammer drill so the ability to put this in my old rotary hammer (A DC212 7/8” Rotary Hammer) makes my life easier. The majority of my work is framing/remodels and this gets the job done. You get a lot of power and versatility. The bits lock in very well, but to get it to grip you have to hold the bottom part below the blue line and twist the textured top. It fit in my drill well, it moves half an inch to compensate for impacting. It’s worth the money, the value is through the roof! Review: Bosch HA3JAW 1/2-Inch 3-Jaw Keyless Chuck with SDS-plus Shank - Initially I wasn't sure whether to get this or the SDS shank keyed chuck, I haven't had any problems with the HA3JAW. It's for boring large holes in wood, and for large drill bits that don't come in SDS shank. The price seems to fluctuate wildly. The rest of the review is a combined one.. I purchased the RH328VC to drill holes in concrete walls, my garage/workshop walls are 8ft high concrete. This looks like it will do the job and be useful for drilling large holes in lumber as well. It's a quality tool, and comes with a decent case which I think is essential, and I don't believe in paying $50+ extra for one. It is heavy (8.25lbs) so I can't see myself using it on a ceiling. I also purchased a HA3JAW keyless chuck to use with large regular shank drill bits at thirty five, this adds another 0.75lbs. When latched into the SDS chuck it has about 1/2" of forward back movement. Apparently this IS normal for an SDS shank chuck or drill bit-"The drill bit is not held solidly in the chuck, but can slide back and forth like a piston. The hammer of the drill acts to accelerate only the drill bit itself, and not the large mass of the chuck, which makes hammer drilling with an SDS shank drill bit much more productive than with other types of shank". This probably means that the optional HA3JAW keyless chuck should only be used in drill mode, even if you have round shank masonry drill bits. The RH328VC case has storage for small parts, drills, etc and also a generous area for coiling up the power cable. The case appears to be an improved design -the one that came with my Bosch 3/8" drill is worn out -the "living" hinges and the latches are all broken on that (the drill still works fine though). This case has seperate hinges and latches. I'm not that familiar with SDS but originally it was named by Bosch 'The SDS bit was developed by Bosch in 1975 and the name comes from the German "Steck - Dreh - Sitz" (Insert - Twist - Stay)'. Both the RH328VC and the HA3JAW, are Made in Germany. ## Features - VERSATILE: The Bosch HA3JAW keyless chuck delivers rotation drilling for masonry, brick, and block - UNIVERSAL FIT: The three-jaw chuck is built for use with all Bosch and competitive brands SDS-plus hammers - EFFICIENT: Keyless ratcheting quickly locks straight shank drill bits into place. - DURABLE: The HA3JAW is built with a steel metal sleeve for maximum rugged durability. - FOR USE: Use only in drill-only mode on all SDS-plus rotary hammers ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0062ICGEM | | Best Sellers Rank | #70,628 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #43 in Power Drill Chucks | | Brand | Bosch | | Brand Name | Bosch | | Capacity | 0.5 Inches | | Compatible Devices | Drilling Machine | | Customer Reviews | 4.4 out of 5 stars 1,981 Reviews | | Global Trade Identification Number | 00000346393200 | | Handle Type | keyed | | Included Components | Unit^Instruction Guide | | Item Diameter | 0.5 Inches | | Item Type Name | Drill Chuck | | Item Weight | 0.01 Ounces | | Lock Type | Independent | | Manufacturer | Bosch | | Manufacturer Part Number | HA3JAW | | Material | Alloy Steel | | Material Type | Alloy Steel | | Model Number | HA3JAW | | Thread Size | 1/2 inch | | UPC | 000346393200 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Bosch - **Compatible Devices:** Drilling Machine - **Item Diameter:** 0.5 Inches - **Item Weight:** 0.01 Ounces - **Material:** Alloy Steel ## Images ![3-Jaw Keyless Chuck with SDS-Plus Shank, 1/2-Inch HA3JAW - Image 1](https://m.media-amazon.com/images/I/61ME7OfbgxL.jpg) ![3-Jaw Keyless Chuck with SDS-Plus Shank, 1/2-Inch HA3JAW - Image 2](https://m.media-amazon.com/images/I/61ir7OGYOVL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Can this be used for hammering (chisel), rotory hammering (bit)? Using regular bits and chisels,** A: I can't speak for the keyless version of the Bosch 1/2" chuck adapter. But I have the keyed version of Bosch's 1/2" chuck adapter! The keyed version, employs a a special chuck body with a sliding shank, that (like an SDS chuck,) transmits the percussive energy directly into the back of whatever tool or bit is installed in the Jacobs chuck. I used my adapter to fit a 30" x 1-3/4 bulb auger, into Dewalt's 18volt SDS+ roto hammer. Then used this combination, for several days, in the rotor hammer mode, without a failure. (A roto hammer fitted with a bulb auger, is my tool of choice when the task is the extrication of woody shrubs, and their gordian root systems!) **Q: Which is better, Bosch key or keyless construction?** A: Keyless is better specially if you start drill and forget key is still in the chuck **Q: Is the SDS Shank removable? Does the chuck loosen when operating in the opposite direction or is there a flat spot to lock the chuck on the shank?** A: Yes, it locks in place just like a bit would. Works great, I used it to mix mortar for 2K feet of floor tile. **Q: How do you lock it into position so that it is not moving up and down?** A: Thank you for your question. The HA3JAW adapter works the same way the SDS-Plus bits work. They lock into place in the chuck.
