Drill Bits for Mushroom Liquid Culture Jar Lids

Drill bits, available in three sizes, for drilling your own mushroom liquid culture jar lids. All of our drill bits are suitable for drilling through both metal and plastic lids. We recommend using these bits with a drill press for the most accurate results.

Available in three sizes, each with different recommended applications:

  • 1/2" inch: (Forstner style) The perfect size for our super heavy duty injection ports. A watertight seal will be formed without the use of RTV silicone.
  • SS-13: (Straight Shank style) This custom sized specialty drill bit is specifically for our 13 mm syringe filters. This specialty drill bit will create the perfect size hole to form a watertight seal between your lid and syringe filter without the use of RTV silicone.
  • SS-25: (Straight Shank style) This custom sized specialty drill bit is specifically for our 25 mm syringe filters. This specialty drill bit will create the perfect size hole to form a watertight seal between your lid and syringe filter without the use of RTV silicone.
