How to Choose the Right Grinding Bit:

When choosing the right stained glass grinding bit, make sure you research which bits are compatible with your grinder because not all grinding bits have universal compatibility.

If you are a beginner artist, it is feasible to use the Quick-Fit Bit or the GelBit as they will simplify your work process. The Quick-Fit Bit has an innovative lock design as it eliminates the need for an Allen wrench, simplifying putting the grinder bit on/off. The Quick-Fit Bit makes it easy to change grits for any artist. The GelBit is an advantage for beginner artists due to the different color identifiers.

If you may be apprehensive to try the Quick-Fit Bit or GelBit, you’re a professional or traditional artist, you may prefer our Brilliant Bits as they are long lasting and very reliable products. For professional artists who use their grinder multiple times a day or week, the Brilliant Bit can withstand multiple projects and resists fatigue due to grinding vibration.

How to Choose the Right Grits:

At Techniglass, we produce four different types of grits that are compatible with a wide variety of glasses.  We have rapid, standard, fine and ultra-fine grits for the grinding bits.

The rapid grit surface contains more diamond particles and appears to be a rougher texture. It is used on thick glass to create shapes. The rapid grit is beneficial to use when making large changes to the glass and then move to the standard grit to smooth out edges and make your glass shape more precise.

Standard grinding bits are for shaping glass. The standard grit is best to have as it is compatible with many types of glass and most preferred by many artists.

Fine grits are used for when you are working with thin breakable glass or glass that can chip easily. Artist prefer to use a fine grit as well as an ultra-fine grit when working with mirrors or any antique glass. Antique glass can be fragile and artist don’t want to risk cracking or breaking the glass. Artists also use fine grits to smooth edges on stained glass pieces. This grit is gentle compared to the standard grit.
