Transform your Makita 2012NB 12" Planer with spiral cutterheads to reap the following benefits:
* Achieve an unparalleled level of finish quality without any unsightly tear-out. The inserts are cleverly angled along the helix in a staggered pattern, resulting in a smooth shear-cut effect even on highly figured hardwood.
* Reduce noise levels drastically thanks to the spiral cutter head's limited contact with the board and minimal knives.
* Enjoy the durability of solid tungsten carbide cutters, which are far tougher and retain sharpness for longer than high-speed steel blades. With four cutting edges on each insert, you can easily rotate a chipped or dull edge 90° for a new, sharp cutting edge.
* Set up your planer with ease, as the indexable carbide inserts are interchangeably precise and ground to tight tolerances. You can swap them out in just minutes by loosening the screws, rotating the inserts 90°, and then securing them with the taper hole locking system.
* Dust extraction is made easier by the smaller carbide inserts, which remove thinner and shorter materials.
* Over time, the use of spiral cutter heads proves to be more cost-effective, with the initial investment paying for itself in a short period.
Spiral Cutterhead Kit includes:
* High tensile strength alloy steel cutter block.
* 40 carbide inserts installed.
* A pair of sealed bearings preinstalled
* 5 extra carbide inserts & 5 extra screws free as spare parts.
really nice result on a bunch of cherry - great product and installation services...

I just installed the spiral head in a new Makita 2012 NB and it was very easy and no need to do any grinding on the planer. I sent Mike a link from youtube that gives a step by step method and it worked great. I will never go back to straight knives and I am now measuring my old Poitras 4400 jointer for a spiral cutter. Great service, Thanks Mike.

No surprises with installation. A little grinding on planer body with die grinder. Wrapped head with masking tape for install.\r\nObvious improvement right away! Planer is much quieter.\r\nHave run thousands of lin. feet through so far. Shavings are smaller so better dust collection. Finish is far superior to OEM knives, don’t have to pay attention to grain direction so much. Our main species are Red & White Oak, Beech, Walnut & VG Fir, No figured grains yet. Overall we are thrilled with the performance of this upgrade. Should have done it years ago! Will never go back to straight knives.

Great product quality and functionality, the cutter sliced through curly grain English oak no problem. The cut quality is far superior to the standard Makita cutter block and the finish is excellent, in fact very little sanding was required to get a quality finish. A small jewellery file was used to remove a burr on the keyway to enable the key to fit correctly but other than that it fitted okay.
Do I need to replace the original bearings? If the bearings in your machine are in good condition, they can be reused by carefully removing them with a bearing or pulley puller. However, if the bearings are tightly pressed onto the shaft, removal may cause damage. To minimize this risk, we recommend replacing old bearings with our greased and sealed bearings, designed for long-lasting performance. For a smooth upgrade, we suggest adding the bearings to your shopping cart before completing your purchase. We provide premium bearings from NSK, SKF, NTN, FAG, Timken. They are renowned for their high quality and performance, designed to provide durability and reliability in various applications If you add the bearings to your order, we will preinstall them for you when premounting is possible, saving you the hassle of doing it yourself.
Do I need to to Add a Few Boxes of Carbide Inserts We provide 5 carbide inserts and 5 screws as spare parts. However, many of our customers choose to purchase additional boxes, as the shipping costs for separate purchases can make it less economical.
Do I need a Torque Wrench? To securely lock the carbide inserts, we recommend applying a torque of 48 to 52 Pound-Inches (or 5.42 to 5.88 Newton-Meters). (Note: 1 Newton-Meter is equal to 8.851 Pound-Inches, and 1 Pound-Inch is approximately 0.113 Newton-Meters.) It is crucial not to apply excessive torque, as this could cause the carbide inserts to crack or explode. On the other hand, using too little torque may result in the inserts not being properly secured, which could lead to cracks, shattering, or uneven height on the cutter block, causing ridges or lines on the board. If one person is responsible for maintaining the machine, they can typically apply the same torque consistently without a torque wrench. However, when multiple people are involved in machine maintenance, ensuring uniform torque application can be challenging. For consistency and peace of mind, we recommend using a torque wrench.
What kind of steel the cutter block is made of? The cutter block is constructed using GB/T 40Cr, a structural alloy steel of the same caliber as ASTM grade 5140, AISI 5140, SAE 5140, DIN 41Cr4, BS 41Cr4, JIS SCr440, and EN 41Cr4.The primary components of this steel are as follows: carbon (C) at a range of 0.37-0.44%, silicon (Si) between 0.17-0.37%, manganese (Mn) within 0.50-0.80%, and chromium (Cr) from 0.80-1.10%. In terms of physical properties, this steel exhibits a tensile strength range of 115-234σb/MPa, a yield strength of 2σ 0.2 ≥/MPa, and an elongation capacity of 65 δ5≥ (%). It also has a HBS range of 123-321 and a HRC rating of 30. This alloy steel is frequently utilized in low to moderately stressed components for machines, engines, and vehicles.
