Customer photo shows our 72" boring bar reboring 4 holes in line on a large bucket. The mag drill is held by our weld-on safety base in case of power failure. Also notice the 2 just bored and sleeved holes above.

All you need is our line boring equipment, a mag drill, welder, grinder and you can do it. But avoid the dangers of long hair and loose clothing.

Q125, Q150, Q175 Line Boring Systems - with drill base adapter:

Made in Chicago, Illinois, USA. Our equipment is the easiest and most economical way to rebore holes round and concentric again. One year warranty against defects in American craftsmanship.The Q125S, Q150 and Q175 setups include everything you need for reboring most holes. It is intended for repairing holes up to 8 inch diameter in heavy construction equipment such as cranes, backhoes, endloaders, excavators and tractors powered by your variable speed magnetic drill press with a 3/4 inch drill chuck. It can also be used to rebore holes in machinery frames, steel mill ladles, bridge support pivots, etc. Our 1.500 inch diameter and 1.750" diameter boring bars hold standard 1/2" square shank carbide lathe machine cutting tools. Our 1.250" diameter boring bars hold standard 3/8" square shank carbide lathe machine cutting tools. The bearing that is built into our Adapter Base bearing will hold the boring shaft load to prevent overloading the bearings in your mag drill. Since 2014 we now add extra mounting holes to allow an extra flange bearing to be bolted directly underneath. The Adapter Base also clamps the magnetic drill in case of power failure. A jacking screw is provided for positioning. Approved by Milwaukee Tool Company Engineers for use with their magnetic drill press. Available in 2 lengths depending upon what is the length of your magnetic base. Our boring bars are made from hard chrome plated induction hardened high tensile strength alloy steel to last a lifetime. Without a thick layer of chrome plating, your boring bar will need to be sanded and/or oiled regularly to prevent rust. The chrome is so hard it prevents scratches or scars on your shaft. The chrome also makes removing weld splatter super easy. That is why we sell only chrome plated boring shafts. No maintenance required. We also can supply .875, 1.00, 1.25 1.50 and 1.75 diameter boring bars separately. Prices do not include shipping cost. Most equipment is in stock and ships the next day or so. Scroll down to see all our different size kits, photos, videos, instructions and options.

Optional powerfeed available at extra cost.

Line Boring Bars Separately:

Our boring bars are hard chrome plated induction hardened high tensile strength alloy steel. The hard chrome means they dont rust, set screws in the cones wont hurt the chrome and weld splatter wont stick. Most sizes are normally in stock.

These tools are used to accurately measure the bored hole without removing the boring bar. Very accurate to within .001". The gauges are spring loaded to expand inside the bore. The size is locked with a set screw using a small hex wrench. The gauge is then removed and a caliper is used to accurately measure the length of the gauge. If you will be doing a lot of bore repair then you will want this.

Cutting Tool Positioner

$199.

Cutting Tool Positioner Image shows how to adjust the Cutting Tool

Two piece gauge that offers an easy way to accurately adjust your cutter height to within .001 inch on the radius. It also holds the cutter while you tighten the set screw in the boring bar against the cutter shank. Set screws onto the cutting tool and adjusts the position up or down by .001" per line of rotation on the outer ring. Works for adjusting the cutter height for holes 2.25" diameter and larger. Need to mount to other end of cutter for holes smaller than 2.5". For holes larger than 2.5" diameter it can be left on the cutter while boring holes. We include a hex wrench for the set screw that is inside the inner collar.

We recommend this for holes 2.5" diameter and larger.

Small Cutting Tool Positioner

$198.

Fits in a inch square hole in the boring shaft and very accurately adjusts the height position to within .001" on the radius. Works for setting the cutter for boring holes 1.75 to 2.5" diameter. Can be left in the boring bar while boring. Works by rotating the screw head against the boring bar. The screw is threaded into the cutter. Each line of rotation equals .001 inch of position change. Much easier than using a dial caliper or dial indicator. Set includes adjuster, 3 carbide cutters and a sharpie marker (to draw a reference line on the boring bar). Extra cutters cost $35 each.

We recommend this for holes 2.5" diameter and smaller.

Adjustable Dial Indicator:

$49.

If you do not already own an Adjustable Dial Indicator, then buying this option could be a no brainer. Every machine shop should have one. This option works great for accurately adjusting your cutter height within .001 inch. The magnet will attach to our mag drill adapter base, or to one of our bearing mounting plates, or to the boring shaft.

The assembly includes:

  • Magnet with V-shaped base and on-off switch
  • Adjustable arms with connectors and fine adjust
  • Dial Indicator - accurate to .001 inch

Good measuring method for all size holes.

Dial Indicator and magnet mounting adapter

$69.

This is much better than it sounds. Includes a Dial Indicator with .001 inch increments, and also includes a magnetic mounting adapter. This solid mounting system eliminates the unsteady attachments normally used with a dial indicator when adjusting your cutting tool height.

Good measuring method for all size holes.

Cutting Tool Micro-Adjuster

$340. (Dial type), $542. (Digital type)

Cutting Tool Micro Adjuster

A very accurate way to adjust your cutter height. Clamps to the carbide carbide cutting tool shank and very accurately adjusts the position. Can be used on either end of the cutter. Works for setting the cutter for boring holes 2.5" diameter and larger. Extremely accurate to within less than .001".

Unfortunately you have to always remove it after each use before boring. The Cutting Tool Positioner is easier to use.

We recommend this.

Set of 2 Slotted Clamping Collars

$119.

Clamping Collars

Reduce the vibration of your carbide cutter with this option. These 2 clamping collars can be attached at any time to reduce cutting tool chatter. They are slotted to fit around the square shank of your cutter. One on each side of the cutter but still allowing access to the set screw in the boring bar to adjust your cutter height. Each clamping collar has a set screw to clamp against the cutter shank. Great way to reduce vibration when boring holes 3.5 inches diameter or larger up to 5.5 or 6" diameter.

We recommend this for 4" and 5" holes.

Facing-Sanding Tool

$294.

Picture of Facing-Sanding Tool Kit

Use to sand and face the damaged boss around a hole and make it like new again. The set includes an 8 inch diameter aluminum sanding disc that screws into our Q150 boring shaft and is designed to spin at 350 RPM. This kit also includes 6 adhesive coarse sanding discs for metal removal and 3 adhesive medium sanding discs for metal finishing. Discs are 8 inches diameter. You can add an 8 inch capacity bearing mounting plate if needed for only $49 extra.

Universal Joint for Mis-alignment

$695.

Universal Joint for misalignment

Used to crudely compensate for misalignment of the Boring Shaft and the Magnetic Drill Press. Comes with Adapter Shaft (shown in photo) to connect the Universal Joint Coupling to your 3/4 inch Drill Press Chuck.

This is not needed for 99 percent of line boring jobs.

Shaft Extender

$495.

Extension tube to connect 2 boring bars together to make 1 long shaft

This tube is specifically engineered to connect 2 line boring shafts together. This will allow you to line bore long distances. Connects the 2 shafts from the Q150XLS, Q150E, Q175XLS to be 9 feet long. Connects the 2 shafts from the Q175XLM or Q175E to be 12 feet long. The outer diameter is 2.25 inches(Q150) or 2.50 inches(Q175). The length is 18 inches. Made from high strength tubing with inner diameter being an exact fit over the shafts.
