Great little set up. Very little sweeping up for you.
Having zero luck tracking down FenceFurniture.

The last thing you want around a drill press and drill bits is the hose or dust port getting in the way of the drill bit or work piece.
A Bell mouth Hood connected to a DC works really well in these situations.
O course if you are using a vacuum cleaner the much lower total air flow means you have to get the suction closer to the drilling action.

I use the dewalt extreme 2 metal drill bits for endgrain regularly. My set goes up to 1/2". I don't know if bigger sizes are available
but they are brilliant drill bits
they look like this

Loving the input here. Thanks again.
Now, slightly off topic but part of the same process.
I have recently bought a new in box mitre saw supplied with what I believe to be a junk 305mm blade.
Very slow going just slicing off 300mm sections of 70mmx35mm radiata pine.
I was borrowing a neighbour's small Ryobi mitre saw and it was like a hot knife through butter.
I can 'feel' the 305mm's bluntness ( or rather lack of manufactural sharpness ) because I have to slowly
push it through the timber piece.
Before I rush out and throw $100 at a new blade, does sound like the supplied blade is not particularly sharp ?

Just a suggestion - check that the blade is not on backwards and the nut is tight.

The blade might be a zero or negative rake, in which case it will take more effort to push no matter how sharp it is. That being said, it shouldn't struggle through pine.

Blade set in correct direction and tight.
It's quite possible that I have been comparing oranges to apples.
All else being equal will an 80 tooth cut faster than a 100 tooth ?
I have been ignoring this aspect.

Official and unreserved apology to Sam at Swart Tools.
I was comparing apples to oranges and blaming you for it.

Hi
I'd suggest you consider an auger bit like this one if you can obtain the size you need. This helps clear the chips from the hole better than a twist drill. The link is to an extra long auger, 230mm.
A "TRUE" brad point bit is harder to grind without a thin grinding wheel or perhaps using a dremel style tool. A true brad point bit looks like this...

Many people (including manufacturers) refer to a pointed drill bit with the cutting edge angles "inverted" like this...
brad point drill tip4.jpg
as a brad point drill bit. This does have a point (depending on the drill purchased) it may or may not be a "brad" point. The brad point being a fine point. This inverted grind is easy enough to do on a grinder, but will not provide the same performance as a true brad point drill bit with "spurs". I don't think the spurs will help a great deal when drilling into end grain, they do however help when drilling across the grain, providing a nice clean edge around the hole, This clean edge can be very useful if you need to drill through melamine or laminate.
The "pretend" brad point drills are a cross between a twist drill and a spade bit.
I purchased a "pretend" brad point drill bit to drill 5mm holes for adjustable shelving. The result was a ragged edge around the hole, not as clean as the result from the Blum 7 spindle drilling head. I purchased a "dowel" drill which is a true brad point drill bit (but only a short drill bit) and the result was a clean edge around the hole.
Anyway, I think the spurs will help keep the drill bit straight when drilling into end grain, but if I was doing the drilling I'd purchase an auger bit. An auger bit usually has the spur.
Good luckKind Regards
Peter

Sorry Peter, but I thoroughly disagree. You might recall the same discussion last year about "fake" brad points where I showed a perfectly clean hole with one of my self-made inverted grind bits https://www.woodworkforums.com/f11/br...28#post2037928

Thank you Peter.
An auger looked great but I was concerned that it would have a tendency to 'keep going'
and would be difficult to stop. I suppose I could fix a strong stop plate on the bottom of
my jig. I tried a speed bore spade bit with a screw tip and while it was great for drilling 'through'
I really had trouble pulling it up. Do you think the auger you are suggesting might offer the
same resistance ?
