SECTOR GEAR & NEW DUAL SECTOR GEAR(DSG)

We have made the following updates to the original version of the sector gear:

1. The logo and packaging box have been changed

2. 5mm holes changed to through-holes

3. Change of sector gear chamfer to 15° chamfer

4. The Bevel Gear shaft has been changed to a new customized tooth shape, with a thicker tooth width and greater torque resistance.

5. The material has been upgraded to 42CrMo/SCM440.

The New sector gear is different from the previous version, the new version changes the position of the Tappet Plate pin, a more reasonable position, delayed Tappet Plate release time, and better performance at high speeds. In the machining, we used customized hobbing tools to improve the tooth shape and mesh better with the piston's rack. The gears are made of 42CrMo/SCM440 steel and are manufactured through six main processes: CNC turning, CNC hobbing, CNC milling, heat treatment, polishing, and blackening.

SPUR GEAR & NEW SPUR GEAR

The whole spur gear is made of 42CrMo/SCM440 material, through CNC turning, CNC hobbing, heat treatment, polishing and blackening process. Gear using turning and milling composite machine integrated processing molding, making the gear more precise, less swing, high-speed operation, less noise, while the gear hardness HRC42-47, the previous version of HRC33-38, hardness and toughness of all together. The blackening process we use makes the thickness of the surface covering layer almost non-existent, which is also one of the reasons why there is no dryness between the gear meshing.

BEVEL GEAR & NEW BEVEL GEAR

Bevel Gear consists of a bevel gear plate and a gear shaft made of MIM technology. Both sides of the bevel gear part and the inner hole have been precision machined to reduce the swing caused by the low precision of the MIM process. The gear shaft is produced using CNC turning, CNC gear hobbing, and straight grain rolling processes. The heat treatment process of the bevel gear and gear shaft is hardened to HRC42-47 and HRC48-52 respectively. The teeth of the gear shaft are relatively thin. In order to avoid brittle fracture, the hardness is slightly reduced to obtain better toughness. In addition, we also specially customized the tool parameters for the gear shaft to try to increase the width of the teeth and try to improve the toughness. A balance between boosting and keeping noise low.

ya get what ya pay for.
Size: 58mm Fits Breville Dual Boiler/Oracle/Gaggia/E61
WDT tool came with bent needles and they are spaced too closely together and are too long to maintain position and bend way too easily and its receiver is a bit short and not weighty enough to be stable with its aspect ratio. Tamper purports to be a calibrated force tamper while it is a simpler spring-loaded depth-setting tamper ground distribution tool has a gap that gathers grounds if it is not perfectly closed. portafilter screen is pretty dang good the dose funnel chamfer is not at the same height as the rim of the portafilter, making me overfill for estimate fits my Casabrews Ultimate setup pretty well. blower bulb is woefully undersized to produce enough force to eject extraneous grounds

Simple, high-quality solution that makes the transition from grinding to tamping much cleaner!
Color: Black, Size: 58mm, Color: Black, Size: 58mm
I wanted to streamline our espresso workflow. I added the Normcore Magnetic Dosing Funnel V2 to our kit because loading up the portafilter & using the WDT was causing a mess on the counter. This funnel stays put and looks great. is it required? No. Does it work great? Yes! The Good: What Works Well Rock-solid attachment: The magnets are impressively strong. It snaps onto the portafilter and doesn't budge. WDT’s Best Friend: It provides the necessary height to use a WDT tool without making a mess. Low Profile: Unlike some "tall" funnels, this one is compact enough to fit under many grinder dispensers while still attached to the portafilter. Premium Finish: The matte black anodized aluminum feels incredibly durable and matches high-end espresso gear perfectly. The Not-So-Good: Price Point: It is definitely a premium option. You can find plastic versions for less, but they won't have the same weight or magnetic security. Pro Tips: Maintenance: This is anodized metal; do not put it in the dishwasher. Just wipe it with a dry cloth or a dedicated coffee brush. Magnet Care: Keep the bottom magnets clean. If coffee oils or grounds build up on the magnets, the "snap" won't feel as secure. Compatibility: Make sure you pick the right size!

Reduces Mess, Lightweight, Strong Magnets, Fit is OK
Color: Black, Size: 58mm
I've been stubborn about buying a funnel - yet another coffee tool to simplify and optimize, right? But, it really does reduce the mess when using the WDT tool. The magnets are quite good, a different brand funnel (with magnets) wouldn't even stick to my portafilter. The fit is OK - it does slide around on my 58mm basket if I move the funnel. But, that hasn't been an issue because the magnets keep it in place. The shape is also a bit more tasteful than most of the generic funnels. Oh, and beware - if you're grinding directly into your portafilter basket (hands-free), the funnel may not fit into your grinder's portafilter-holder. This was the case with my DF54 grinder. Overall, I'd say it was worth the extra ~$4 USD over generic competitors.

Great coffee dosing funnel
Color: Silver, Size: 58mm
Normcore products seem to all be high quality. This funnel works very well. Strong magnets hold it securely to the portafilter. My only small complaint is I wish it was just slightly taller on this 58mm version. Just a few millimeters of additional side height would be a great advantage at times when the fine ground coffee decides to come out of the dosing cup in a clump. This current model still makes it much better than with no funnel and does the job quite well.

Very nice funnel
Color: Black, Size: 58mm
58mm fits perfect on a Pullman basket. Good quality as well. Be careful the magnets are strong the benefit of this design though is, it is a tamp through. Keeps the mess to a minimum transferring from dosing cup to portafilter, keeps your grounds in the basket during distribution as well.
