Unlike conventional scroll saw blades that only cut on the forward stroke in one direction, spiral blades have teeth running all the way around the blade — allowing cuts in any direction without rotating the workpiece. This is a significant advantage when working with large or awkward workpieces that are difficult to maneuver.\u003c\/p\u003e\n\n\u003cp\u003eThe plain-end (no pin) format allows the blade to be threaded through a 1.5mm (1\/16\") pilot hole for interior cutouts — essential for fretwork, inlay work, and any cut that starts inside the workpiece boundary.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-direction cutting\u003c\/strong\u003e — spiral teeth all around the blade; cut in any direction without rotating the workpiece\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlain-end (no pins)\u003c\/strong\u003e — threads through a 1.5mm pilot hole for interior cutouts and fretwork\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge workpiece advantage\u003c\/strong\u003e — eliminates the need to rotate heavy or awkward pieces during cutting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-pack\u003c\/strong\u003e — generous supply for extended scroll work\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eInterior cutouts and fretwork (blade threaded through pilot hole)\u003c\/li\u003e\n\u003cli\u003eLarge workpiece scroll cutting without rotation\u003c\/li\u003e\n\u003cli\u003eOmnidirectional pattern cutting in wood\u003c\/li\u003e\n\u003cli\u003eInlay and marquetry work\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e No. 28747\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade type:\u003c\/strong\u003e Spiral (all-direction cutting)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade end:\u003c\/strong\u003e Plain-end (no pins)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot hole required:\u003c\/strong\u003e 1.5mm (1\/16\") minimum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 12 per pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eScroll Saw Blade Types — Which to Choose\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Plain-End \/ No. 28747 (this blade)\u003c\/strong\u003e — all-direction cutting; for large workpieces and interior fretwork cutouts\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/proxxon-scroll-saw-blades-for-dsh-e-10-tpi-pin-end-12-pack-thicker-wood-soft-materials-no-28741\"\u003ePin-End 10 TPI (No. 28741)\u003c\/a\u003e — coarse; fastest cuts in thicker wood and soft materials\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/proxxon-scroll-saw-blades-for-dsh-e-18-tpi-pin-end-12-pack-wood-plastics-no-28743\"\u003ePin-End 18 TPI (No. 28743)\u003c\/a\u003e — medium; versatile all-rounder for wood and plastics\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/proxxon-scroll-saw-blades-for-dsh-e-25-tpi-pin-end-12-pack-nf-metals-grp-plexiglass-wood-no-28745\"\u003ePin-End 25 TPI (No. 28745)\u003c\/a\u003e — fine; for NF metals, GRP, Plexiglass, and thin materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWorks Well With\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/proxxon-delta-sander-ozi-e-no-38520\"\u003eProxxon Delta Sander OZI\/E (No. 38520)\u003c\/a\u003e — for sanding tight inside curves after scroll cutting\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/proxxon-belt-sander-bs-e-no-38536\"\u003eProxxon Belt Sander BS\/E (No. 38536)\u003c\/a\u003e — for smoothing scroll-cut edges\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eReturns can only be accepted for unused product in its original packaging.
