Milwaukee® 48-20-2160 4-Cutter Vacuum Drill Bit, 7/8 in Drill Bit, 18 mm SDS-Max Shank, 15-3/4 in D Cutting, 23 in OAL
The Milwaukee® vacuum drill bits reduce airborne silica dust and provide increased productivity during the chemical anchor preparation process. The combination of dust extraction holes at the bit tip and the hollow shaft design allow dust to be removed through the bit while drilling holes, reducing airborne silica dust in the process. Milwaukee® Vacuum drill bits are an OSHA table 1 compliant solution when used with dust extraction vacuums. Additionally, vacuum drill bits leave clean holes which are ready for the chemical anchor installation, removing the need to use standard drill bits with the blow-brush-blow cleaning method, delivering up to 2x faster chemical anchor preparation. The 4-cutter tip designs delivers durability in concrete and concrete with rebar applications. The universal adapter fits most common dust extractor attachments.
PTI 10B-31B Single Strand Hub Type B Roller Chain Sprocket, 20 mm Dia Bore, 163.9 mm OD, #10B-1 Chain, 31 Teeth, 15.875 mm Pitch, C45 Steel
Hub type metric sprockets are available with a minimum plain bore (pilot bore) and some stock finished bore sizes. Any shaft size is possible with our custom bore and keyway capability. Sprockets with hubs are typically fitted to the shaft as a clearance fit. They are held in place with two set screws and a keyway. Clearance fits are popular for light loads and slow speeds. A press fit (or shrink fit to the shaft) is usually preferred for higher speeds or heavier loads as they fit to the shaft more securely than a clearance fit sprocket. Depending on the clearance of the shaft fit, sprockets may work slightly on the shaft causing possible fretting or shaft wear. All sprockets are available with hardened teeth from stock or on request. Press fits usually require the sprocket to be heated for installation to expand the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a tight grip. A set screw can be used to secure the key. The TL taper bushed sprocket will function like the press fit sprocket and is generally easier to install.
