Auniwaig Forstner Drill Bits
- The bit includes a center point which guides it throughout the cut and incidentally spoils the otherwise flat bottom of the hole.
- The cylindrical cutter around the perimeter shears the wood fibers at the edge of the bore, and also helps guide the bit into the material more precisely.
- Made from high quality carbide tungsten steel and being hot-treated,sharp edge,high hardness, accurate positioning,high precision,smooth cutting,impact resistance,high toughness.more smooth,less noise.
- For drilling flat bottom holes with no chippings in any thickness of soft wood. For drilling holes in any direction and making arched openings. For drilling partially overlapped flat bottom holes for easy mortising.
- Suitable for pistol drill, bench drill, vertical drilling machine hand held electric drill, stand motor-driven drilling machine and mobile ribbon type magnetism drilling machine,etc.Perfect used for drilling precision holes in most of different types of wood, such as drawer, mounting spherical door shoot tip, perforation on wood products, and plastic products etc.

Instructions for Woodworking Hole Opener :
- 1. Put the hole opener into the electric drill before use and confirm that it is firmly clamped before it can work.
- 2. Keep the vertical angle with the workpiece when working. After the hole opener drills through the workpiece, the workpiece should be withdrawn while the hole opener is rotating.
- 3. Please clean the sawdust in time to avoid opening failures during continuous work.
- 4. Workers should wear corresponding protective equipment when working to protect them from working safely, and apply rust oil after use to extend the service life.

- The cutting material must be fixed, and the drill bit should be perpendicular to the material. It will damage the tool or the material if the cutting material moves during the drilling process.
WIDE APPLICATIONS
Application:
- Suitable for cutting holes onto most low hardness wood and wood products. Can easily enlarge existing holes and bore any arc of a circle. Drills flat bottom holes, pocket holes, and overlapping holes.
- Great for boring concealed hinges and door locks. The cemented carbide tip is designed to cut through hole cleanly. Can be used for wood products perforation, mounted spherical door shoot tip, drawer, plastic and wood products, plywood, etc..
- Suitable for bench drill, vertical drilling machine, CNC carving machine, etc. The bit in the positioning is required to very low speed, and then gradually accelerate after complete position. Add water for lubrication and temperature reduction when drilling.
- NOTE: This forstner drill bits is widely used on desktop (fixed) equipment, and can NOT be used on handheld power tools (such as hand drill or electric drill).

I needed a 40mm bit to only cut four holes. At this price point I decided to give it a shot with my expectations set a little low. The bit was quite sharp right out of the bag and performed well. Not sure how it will hold up long term but, for my purposes, it was a good value.

I made some wood coasters and wanted to integrate a bottle opener in the bottom of them. The metal bottle openers are 40mm. I couldn't use a regular spade bit because the point would drill all the way through the coaster. This bit worked perfectly!! Smooth, even, didn't slip at all in my drill.
