Pepetools IronBrush - Pneumatic Engraving Tool
HIGHLY RECOMMENDED

Amazing customer service, guidance, and products! Bought two scales from them - the scales were awesome and the customer service - simply stellar. HIGHLY RECOMMENDED!!!!!!!

Excellent Professional Scale - Very Satisfied

Fast shipping, item is top notch. I've used Ohaus scales for years professionally and love them. This is not a kitchen scale. It's Legal For Trade and designed for accuracy beyond what would ever be needed in a casual setting. Also important... weighing best practice: You cannot use scales such as this in rooms with moving air (fan, ceiling fan, lots of nearby motion). The scale picks that up as weight. That's not an item defect.

Absolutely worth the cost

I love cheaper tools, but one thing to not skimp on is a disc cutter. The cheap ones don't cut cleanly, so you have to spend a lot of time finishing them to buff out marring, or just discard failed attempts because it won't cut cleanly. You also spend so long cutting your fingers up trying to push the die out of the cutter! But nice disc cutters like Pepe Tools- so worth it. I use it so much more than I thought I would, and it clamps down so it holds the metal tight and cuts effortlessly each time.Don't waste your time or money on the cheap ones, it's just not worth it. Get a quality Pepe cutter and you only have to buy it once! Totally worth it.

Best tool and quality

This is my second disc cutter as I purchased directly from Pepetools a circle cutter. The company is very personable and appreciates the business. Personal thank yous. I am impressed with the quality and ease of use. I am punching my ovals and circles on a 20 ton press. Super fast and easy. I highly recommend this item and also be sure you use their lubricant to keep your cutters in good shape.

Excellent product

Does a great job.Don't be put off if one or two of the dies need a little tweeking.Sometimes they don't fit perfectly, but all you to do is sand the insideof the hole, not the actual die.
