| Q1) | Which model is best for cutting holes in lathe and plaster? |
| A1) | Any of the X-models will cut through lathe and plaster, though if there is a metal mesh backing for the L&P it is best to use the Hole Pro carbide blades |
| Q2) | How many holes can I cut with one blade or set of blades? |
| A2) | The blades are designed to cut up to 100 holes in materials such as wood or sheetrock. The metal cutting hole cutters are designed to cut up to 50 holes. This is an average, as the circumference of the hole affects the amount of material being cut |
| Q3) | How many blades come with the hole cutter? |
| A3) | Each hole cutter comes with 2 sets of blades. One set of tungsten carbide blades are installed in the hole cutter. One set of HSS (high speed steel) blades are in the upper right hand corner of the carry case. Both types of blades are user replaceable and can be ordered separately |
| Q4) | Are there any advantages over the adjustable hole cutters when compared to conventional cup style hole saws? |
| A4) | Conventional cup hole saws cut only one size hole. For multiple size holes one needs multiple cup hole saws that need to be attached to a mandrel for use. The Hole Pro adjustable hole cutters enable an almost infinite range of hole diameters to be cut using a single tool. |
| Q5) | Is there kickback with the Hole Pro hole cutters? |
| A5) | The Hole Pro adjustable hole cutters greatly reduce the chance for kickback as compared to conventional cup style hole saws which with their side walls that can easily stall and kickback. |
| Q6) | How do I cut through materials thicker than 1 inch? |
| A6) | It is possible to cut materials up to 2 inches in thickness by first cutting from one side of the work piece and then using the center drill to cut through the other side using the center hole to keep the holes aligned. |
| Q7) | How does the high impact plastic dust shield work? |
| A7) | The shield remains stationary against the work being cut helping to keep the drill aligned while the rubber edge seal keeps the dust and shavings inside the collector slots. The shield operates like a portable drill press, making the hole being cut perfectly circular. |
| Q8) | How do I clean the Dust shield and the Yellow Gasket after they have gotten dirty? |
| A8) | I notice that after a period of using the Hole Pro's with dust shields, the sheetrock ceilings start leaving dirt behind. 1) To clean the inside of the shield use a damp cloth and NO WATER near the center bearing race, or the bearings can cease 2) To clean the yellow gasket, leave it in the shield and take a damp sponge with a little dish soap and wipe away any residue picked up from the ceilings and then wipe the gasket dry |
| Q9) | I am needing to cut a 8 7/8 inch hole in fiberglass on my boat to add a speaker, which is the best twin blade adjustable hole cutter for this application? Also when I'm using it do I need to go in reverse? I've heard when cutting fiberglass with a normal hole saw going in reverse helps prevent splintering of the fiberglass |
| A9) | The issue with the X-230+ twin blade adjustable hole cutter (which cuts holes up to 9-1/4 inch diameter) is it needs to use the shield to keep the tool perpendicular to the work surface being cut. You need clearance for the 11 inch outside diameter shield used by the X-230+. With marine speakers the majority use a smaller hole so an 8 inch speaker may only need a 6 inch hole as more of the speaker is mounted above the surface versus behind the wall, like speakers in a ceiling behind sheetrock. Something to check before making the holes for them. The X-148 twin blade adjustable hole cutter can cut 6 inch diameter.holes has an 8 inch outside diameter shield. |
