A new chisel has just one bevel, usually 25 degrees. But the tool should be sharpened at 30 degrees, which creates a new bevel.
What is the correct angle when honing chisels and plane blades?
The primary bevel for chisels and plane blades is normally 25 degrees (a time-tested angle). If you look at the blade diagram above its perfectly acceptable, from a sharpness perspective, to hone the primary bevel flat and hone the back of the blade flat and where these two meet you can achieve a sharp cutting edge.
What angle are most chisels?
Standard bench and butt chisels are traditionally ground at the factory to 25°, and this is fine for most work, but the edge will last longer if you add a 5° microbevel to make a 30° cutting angle.
Do you need a micro bevel on a chisel?
The short answer is, No, micro bevels are not necessary with a Tormek. Microbevels are useful expedients for bench stone sharpeners. The idea is that you grind the entire bevel once and do touch up sharpenings with only a small fraction of the bevel.
Do you need a secondary bevel on a chisel?
Chisel care and sharpening To produce a perfect cut and to obtain the best from a bench chisel it is advisable to use a secondary bevel, sometimes known as a micro or honing bevel. This bevel is normally approximately 5° greater than the primary or main bevel angle.
What is the honing angle?
A honed edge is nothing more than the intersection of two flat steel surfaces that meet at an acute angle. The cutting edge (or honed bevel) is usually a thin strip of polished steel at around 30°.
What are the two angles on a chisel?
Chisels have two blade angles. The shallow, long angle which is usually set to 25°, is called the grinding angle as the chisel is ground down to this angle when first made. The second angle (usually 30°) is called the cutting angle and allows for easier sharpening of the chisel itself.
What is the angle of cold chisel?
The proper angle (general usage) for cold chisels is 60 degrees, increase the angle somewhat for harder metals and decrease somewhat for softer metals.
What angle are narex chisels?
A paring chisel should have a low bevel angle to help reduce the force needed to make a clean cut. Narex did not overlook this detail and these lovely tools come with a 20° bevel right out of the box.
Can you sharpen a chisel with a grinder?
You can sharpen your chisels on a bench grinder. Your bench grinder must have enough power and the correct type of stone. More importantly, you must use techniques that maintain the correct bevel and avoid overheating the steel in your tool, which can soften the cutting edge.
Is secondary bevel necessary?
Absolutely, depending on how you use your knife. I’m guessing you mean what is most commonly referred to as a micro bevel since you say specifically the edge. Technically the secondary bevel is your edge, where as the primary bevel is the main grind down from full spine thickness.

Do you need honing guide?
The honing guide is useful if you want to achieve an exact angle, however there is a bit of leeway when sharpening as chisels can be sharpened anywhere between 25-35° and plane blades can be sharpened anywhere between 25-30°.
What angle do you sharpen planer blades?
Creating the grinding bevel with a grinding wheel makes sharpening easier and faster. The angle of the grinding bevel is about 25 degrees for a plane blade and as low as 15 degrees for a chisel – there is no standard angle. Use a slow speed bench grinder with a cool-cutting wheel.
What is the inclination angle of chisel to cut mild steel?
There are five common types of chisels.The upper part of a chisel is chamfered to an angle of 10° to 12° Material to be cut Point Angle Angle of inclination Cast iron 60° 37° Mild steel 55° 34.5° Brass 50° 32° Copper 45° 29.5°.
How do you sharpen a chisel without a honing guide?

What is the difference between hot & cold chisel?
Hot Chisel Since heated steel is many times softer than cold steel, these chisels are not typically hardened or tempered. They are of roughly the same size and shape as cold chisels, but feature a blade that is cut at a 30-degree angle, making them virtually useless for other cutting tasks.
Do you put a secondary bevel on a mortise chisel?
Blade Bevels Our mortise chisels have a 25° primary bevel for good wedging action when cutting deep mortises. The 35° secondary bevel provides good edge retention while withstanding the extreme stresses involved when cutting across the grain.
What is the bevel angle on a block plane?
The standard block plane has a bed angle of 20°, which together with the blade micro-bevel angle of 25°, results in an effective cutting angle of 45°.
