What to Look Before Buying a Lock Miter Router Bit:

best 45 degree lock miter router bit

From the list, it’s clear that there are many quality lock miter router bits out there. However, not every product will qualify as the best lock miter router bit for your project.

One reason for this is that different types of projects require a certain type of bit. Thankfully, certain factors can help you choose the ideal router bit for your woodworking project. They include; 

Shank size

In a lock miter router bit, the shank refers to the cylinder part that goes into the router’s collet. Generally speaking, router bits either have a ½” shank or ¼” shank. Some routing machines only accept ¼” shanks, but there are models that accept both sizes. 

Either way, it’s important to consider the bit’s shank size before you choose a certain tool kit. In essence, ½” shanks offer better stability, flexibility, and durability than their ¼” counterparts. Also, they vibrate less during use, giving users a better level of control. 

¼” shanks, on the other hand, are more affordable than ½” shank bits, making them a great option for beginners. However, due to their smaller diameter, they jump around more compared to the ½” shanks. As a result, they usually have less precision and inadequate control. 

Build quality

The best way to determine the build quality of any tool is to check its building material. In most cases, router bits are either crafted from carbide or HSS (High-Speed Steel). 

For starters, HSS bits have high heat tolerances since they’re crafted from carbon steel. Also, they’re more affordable, making them a great option for beginners or infrequent router users. Even better, they can withstand more impact damage compared to the carbide router bits. 

On the contrary, carbide bits are either carbide-tipped or entirely coated in carbide. More notably, they’re more durable than HSS bits but more vulnerable to impact damage.

All in all, most professional woodworkers claim that tungsten blades and C3-grade micro-grain carbide material make the best lock miter router bits. 


Not all router bits can cut through plywood, wood, and other kinds of materials. For that, it’s important to consider the types of material you’ll be cutting frequently before you choose a certain woodworking tool.

Thankfully, some lock miter router bits are ideal for cutting through various types of wood. Choosing that type of router bit will give you adequate versatility, allowing you to use the tool for various woodworking projects. 


Most lock miter router bits are either compatible with handheld or table-mounted routers. So, if you already have a router in your workshop, make sure you choose a bit that is suitable for that machine.

Luckily, some bits can be used with both types of routing machines. This will allow you to choose the router with different types of routers out there.

1. How do I decide which lock miter router bit to use?

If you have a certain project in mind, choose the bit that is best suited to it. Consider getting a few straight bits (1/4″, 1/2″, and 3/4″), a few round-over bits (maybe 1/8″ and 1/4″), a rabbeting bit with replaceable bearings of various sizes, a 45-degree chamfer bit, and an ogee bit if you’re putting together a beginner set.

5. How to sharpen router bits?

You should take your router bits to a professional sharpener to give them the sharpest edge for the task. They’ll be able to keep the bit’s right cut and shape while sharpening it to like-new levels.

If you don’t have access to a sharpener, diamond hones may be used to remove a thin coating of the cutting blade’s two edges. Stroke both sides of the bit equally to maintain the bit balanced.

6. How to use a 45 deg lock miter router bit? 

First, properly attach the 45 deg lock miter router bit to a routing machine. More importantly, make sure you work on the specific project of material the bit is designed for. Now, alight the router with precision and slow feed it passes it through the material. 

7. Can you use lock miter router bits on plywood? 

Locker miter bits can be used to work on plywood. However, it’s important to consider the quality of the plywood you’re using. In essence, cabinet-grade plywood is recommended since it provides decent lock miter joints. 

8. How strong are lock miter joints?

Mitered joints are some of the weakest joints in woodworking projects. For that reason, it’s important to strengthen them by gluing end-to-end grains. Alternatively, you can fasten with mechanical fasteners like dowels, nails, and screws. 

9. What can you use a lock miter for?

Lock miters are used for various woodworking projects. For instance, you can use them to make seamless corners with plywood and assemble cases. Moreover, you can use them to make furniture legs or other posts.
