Whether drilling dowel holes or standard fixing holes, using this drill guide will ensure each and every hole is straight. Having worked accurately, use an awl to start the hole, place the tip of the 1/8″ (3mm) bit in the hole and rotate the bit just enough to locate the centre of the hole. The non-slip padding holds the DrillBlock in place while preventing both slipping and marring on work pieces. Once I needed to drill 4 7″ precise parallel holes on a wall based on a template and was able to do it with pretty good success by taping it to the wall.

We could then drill the hole, a counterbore sometimes used a bush to guide a tap if the hole was to be threaded.The company's registered address is Accsol House High Street, Johnstown, Wrexham, LL14 2SH, United Kingdom. Rubber buffers provide reliable grip, with inegrated V-slot for easy positioning on round material or edges. All blocks have alignment slots for SAILSetc standard goosenecks and metal bodied ball raced goosenecks to ensure alignment between the gooseneck and the holes. The Milescraft Drill90PLUS™ right angle drilling and screw driving attachment is perfect for drilling those hard-to-reach wall studs and floor joists, as well as a host of other applications. The bushing block is held at a tight tolerance and allows you to drill a hole 90° to any surface, centred on a round item or even directly into the corner of your project.

Requiring no separate guide bushes, each drill bit is guided within the hardened drill block, precision machined to the tightest tolerances to ensure 90° alignment to the workpiece. The guide block is beautifully finished with a black electro-coating, for wear and corrosion resistance. Portable and pocket-sized, this guide block will ensure perpendicular drilling alignment wherever you go. The centre lines also ensure accurate alignment, while the non-slip padding holds the DrillBlock in place while preventing both slipping and marring.

Surprisingly taps are bigger than size by a few thousands to give a little clearance on the crest of the thread, obvious when you think about it though.

A single block can be used to create the row of accurately spaced and aligned holes for the Z hooks used to adjust the sheets on main and headsail booms - 5 mm spacing. The pre-drill bit inserted into the marking keeps the position, so that you can hold the base body by hand alone for drilling. All bit sizes and centre lines are deeply recessed within the body of the block to ensure that they will never wear away over time.The bushing block is held at a tight tolerance and allows you to drill a hole 90° to any surface, centered on a round item or even directly into the corner of your project. Centre lines for each bit run the full length of the jig, on all working faces, ensuring accurate placement against layout lines on the workpiece. You could also start with two separate pieces of wood, as long as they are square and the same height.
