Silverline Morse Tapered Guide Diamond Core Drill Bit 8mm 200mm 769992

Silverline Morse Tapered Guide Diamond Core Drill Bit 8mm 200mm

Barcode: 5055058104403

MPN: 769992

Size: 8mm Width x 200mm Long

Overview:

8mm x 200mm Morse Tapered Guide Diamond Core Drill Bit designed to provide accurate, stable starting when using diamond and TCT core drilling systems. Featuring a tungsten carbide tipped cutting point, it helps guide the core barrel into masonry with improved control, reducing wandering and improving hole accuracy especially on smooth or hard surfaces. The Morse tapered shank is made to suit compatible Morse taper arbours, while the black oxide finish adds a dry rust-resistant coating for better durability in storage and regular site use.

Morse Tapered Guide Core Drill Bit 8mm x 200mm – Key FAQs

• What is a Morse tapered guide core drill bit used for?
  It’s used as a guide/pilot within a core drilling setup to help start holes accurately and keep the core barrel aligned during the initial cut.

• Is this bit for standard hammer drilling?
  No, it’s intended for use with compatible Morse taper arbours and core drilling systems. For general hammer drilling you’ll usually need an SDS or straight shank masonry bit.

• Can it be used with diamond and TCT cores?
  Yes, it’s designed for use with both diamond and TCT core systems where a guided start improves accuracy and stability.

• What materials is the tungsten carbide tip suitable for?
  The carbide tip is suitable for masonry drilling applications, helping provide durability and consistent performance when guiding core drilling into mineral substrates.

• Does the black oxide finish do anything practical?
  Yes, it adds a dry rust-resistant coating that helps protect the bit during storage and regular use, especially in damp site conditions.

• Why choose 8mm x 200mm for a guide bit?
  The 8mm diameter provides a stable pilot size, while the 200mm length offers useful reach and guidance when starting deeper core drilling operations.
